Silver medals are granted to innovative and practical developments that bring significant improvements to performance, quality, function, safety, environmental impact and energy consumption.

The Case IH Advanced Feedrate Control uses forward-looking radar sensors to scan and assess the density of the crop before it enters the machine, rather than during the threshing process like most technologies.

The information generated by the four header-mounted radar units, which measure the complete plant mass from the ground up for a highly accurate crop density assessment, is used to automatically adjust key settings such as forward speed for the crop volume the machine is about to ingest.

As a result, combine forward speed and engine load are maintained as closely as possible to the desired level, maximising output without the risk of blockage. In addition, experienced operators are able to get the maximum from their machine, while those less experienced can be more confident they can push the combine without fear of it blocking.

The proactive Advanced Feedrate Control has the potential to boost workrates by up to 20%, as operators are able to work at faster ground speeds when compared with a combine fitted with the established reactive automated feedrate intake.

The system’s greater consistency of throughput increases harvesting speeds, minimises losses and improves grain quality, while reduced blockage risk improves safety and minimises inconvenience and downtime.

The system is fitted with the VariCut header, paired with the Axial-Flow 7160 combine displayed at Agritechnica 2023. In addition to Advanced Feedrate Control, the new models incorporate full AFS Harvest Command connectivity.

“The Agritechnica awards panel’s recognition of the benefits offered by this development is really gratifying,” said Peter Friis, head of Combine Business for Case IH in Europe.

“We set out to design a feedrate control system that would be much more proactive than current available systems, and Advanced Feedrate Control is exactly that, providing the ability to get the most from the combine’ potential regardless of operator experience, enabling users to maximise output in short weather windows without risk of overloading.”

The event was in late July, a short distance from the Claas company’s Harsewinkel headquarters. Claas previewed the new tractors during an ambitious evening presentation and then demonstrated in the field the following day. Unfortunately, the weather was like that of the UK in late July; chilly with frequent showers slowing harvest progress and preventing the new combines working for the event.

All the new products will be displayed at Agritechnica this November, but some are available to order now.

Small tractors with wide appeal

Three new series of small tractors have been added to the tractor line-up.

The entry Elios 200-series includes four models from 75–103hp. The base Elios 210 comes in cab or platform versions, and Elios 220, 230 and 240 models are available only with cabs. You can upgrade a base (24-forward/12-reverse), four-speed, three-range, two-mechanical ratio mechanical transmission with Twinshift (two-speed powershift) and an electro-hydraulic Revershift clutch-less reverser.

Rear linkage capacity is 3.2t and the gross vehicle weight is 5.1t, and the tractors have 30in rear wheels. Claas describes the Elios 200 models as ideal for simple yard tasks, with or without the optional Claas front loader.

A line-up of three Elios 300-series models starts at 85hp. They feature a five-speed transmission (30 forward/15 reverse) with Twinshift powershift which increases tractive power by 20%, and the Revershift reverser as standard. A clutch activation button on the back of the main gear shift lever eliminates the need for the foot clutch when changing gear. Optional Smart Stop disengages the transmission to bring the tractor to a standstill when the foot brake is applied. The transmission re-engages drive when the brake pedal is released.

Two Axos 200 models with outputs of 92 or 103hp slot in directly below the current Arion 400-series. These share the transmission of the Elios 300 models but have higher lift capacity and greater payload capacity than the Elios models. They are also equipped with rear wheels and tyres up to 34in. Axos models remain ideal for yard work with a 2.62m overall height, and an impressive 3.79m turning radius.

Shared engines for both types

All the new tractors except the base Elios 210 share the same FPT 3.6-litre, 4-cyl engine. They also include a wastegate turbocharger, intercooler and viscous fan for versatility and efficiency. These tractors achieve rated outputs from 83–98hp at 2,300rpm and produce maximum 85–103hp at 2,000rpm. Full engine torque is available across a wide rev range. The Elios 210 has a slightly smaller FPT 3.4-litre, 4-cyl engine delivering 75hp and 309Nm of torque. All models use SCR (AdBlue) to meet latest emissions requirements. One engine speed memory is standard. Two speed presets are an option – adding convenience for working with PTO-driven or hydraulic-powered implements.

Capable hydraulics

Standard rear lift capacity is 3.200kg for Elios models, and 3,350kg for the two Axos models. Front loaders with 3,200kg lift capacity are available. Hydraulic oil flow rates of 87 litres/min are standard but an optional third pump increases flow to 114 litres/min for faster cycle times. With the additional pump, an electrohydraulic operating system is available for Elios 300 and Axos 200 models and these tractors can be fitted with up to four spool valves.

Standard PTO is 1,000/540, but 540/540E is an option, and a front PTO can also be specified for the  front linkage with 1,000/540E and electro-hydraulic engagement.

Loader options

Claas loaders with mechanical or hydraulic levelling are available. There is a choice of operating systems to suit the application. E-Pilot S provides fingertip control of the loader only, whereas the Electropilot joystick can also operate hydraulic functions and rear implements. It contains direction change buttons too when Revershift is fitted.

Comfortable and functional

Elios 300 and Axos 200 models have a flat cab floor. Air conditioning and an air-suspended seat are options. A passenger seat is standard, and the steering wheel has height and angle adjustment. They display operating information on a 4.2in digital console behind the steering wheel. The display is also used to adjust functions such as the rear linkage operating speed, and spool valve flow rates and timings.

Power tractor – 650hp flagship

At the other end of the Claas tractor line-up, the Xerion 12-series provides a new option for large agribusinesses and contracting operations. There are two models – the 12.590 with up to 585hp, and the 12.650 with 653hp and 3,100Nm of torque.

Both models have a rigid chassis and four equal-size wheels or tracks and front and rear axle steering. Claas describes the tractors as highly efficient for the toughest draft work.

UK buyers are unlikely to choose wheeled versions as they need dual 800/70R42s to transfer the massive power to the ground. This makes the tractors excessively wide for UK roads. The much narrower four-tracked Terra Trac variant will therefore be the preferred option.

Low engine speed concept

Power is from Mercedes Benz 6-cyl, 15.6-litre engines which fit perfectly with the Claas low engine speed concept 2.0 strategy. Equipped with compound wastegate turbochargers, both models produce maximum power from just 1,600rpm and maximum torque down to 1,300rpm. Idling is at just 650rpm. Massive cooling packs maintain efficiency with the help of a reversible fan.

Drive and traction

The new Xerion design helps maintain 50/50 front to rear weight distribution to maximise traction. The 1,400-litre fuel tank is centrally mounted so weight distribution doesn’t change as the fuel level reduces.

The transmission, as would be expected, is a Claas CMatic CVT unit. Benefits of using CVT include gentle drive take-up which reduces shock loads on implements when starting off or altering speed. The new transmission is designed so that operators can utilise the full power for any application. Maximum torque is available from the minimum speed of only 50m per hour.

There are four drive modes with automatic selection. The drive management system transmits power continuously to both the front and rear axles and ensures maximum soil protection – regardless of the steering angle. This means that full traction is available even on sloping ground or when negotiating field obstructions.

The Terra Trac achieves a maximum 40kph transport speed at 1,400rpm. The wheeled version has a top 50kph road speed which is unique in its power class.

Technology maximises efficiency

Like Claas Arion and Axion conventional tractors with CMatic transmission, the new Xerion is available with a similar Cemos process optimisation system. This assists the operator by optimising power transmission, drive management and suggesting ballasting strategies based on the task and working conditions. You can achieve more than 10% fuel savings by using the system. It can recommend settings to increase soil protection too, as well as maximising working efficiency.

Phenomenal hydraulics

Up to three load-sensing pumps supply up to 537 litres/min at 1,900rpm. This means that even the largest drills with high hydraulic flow demands can be operated at low engine speeds, saving fuel. Up to
eight double-acting circuits can deliver up to 140 litres/min each. Cebis terminal displays flow rates for each spool.

New tracks

The new Terra Trac track assemblies have a positive drive, with at least eight drive lugs always engaged. There are two auxiliary steering cylinders per axle, and the track units are in two parts with rubber blocks between the undercarriage and main frame to absorb shocks and vibration. Two pairs of mid rollers on bogies adapt to ground undulations to maximise the footprint and traction. The Camso-manufactured tracks are available in 762 or 914mm widths.

Steering modes include standard trailed rear-wheel steering, four-wheel steering with the front and rear axles. These react simultaneously and there is also a reduced crab steering mode ideal for silage clamp applications. Dynamic steering can be selected – reducing steering wheel turns by 50% for fieldwork.

Largest cab of the range

The cab is like larger Claas Lexion and Trion combines, but it is extended by 27cm at the front giving even more space. The steering column has available footrests, and in the right-hand front corner by the A-pillar for use when the seat is rotated 40 degrees for an improved view of the rear implement.

Control is through a CMotion joystick; like Claas combines, and monitoring and set-up is through a Cebis touchscreen terminal.

The cab has four-point suspension. The company’s demonstration drivers at the event suggested that ride quality on- and off-road is exceptional and superior to a wheeled tractor, especially over rough ground.

Precision farming

A full range of Claas precision farming applications are available. The Cemis 1200 12in display allows remote transfer of field maps and guidance lines and is used for strategies including section control and variable rate applications.

Smaller combines with extra performance

There are two new Evion five-walker models, the Evion 410 and Evion 430 – both powered by Cummins 6cyl engines and using the Cemis 700 control concept. Replacing the discontinued four-walker Avero and smaller Tucano models the new combines slot into the range directly below the new Trion series.

The Evion has a 600mm threshing drum and a synchronised impeller combined with five 4.4m long straw walkers and a feeder housing 1,420mm wide. This gives a concave area of 0.95m2 and a separation
area of 6.25m2 provided by the straw walkers.

The Cemis 700 terminal infinitely adjusts the threshing drum speed between 480–1,150rpm. Like the larger combines, the concave clearance is also adjusted from the cab and has blockage protection. A Multicrop concave is standard so changes are rarely needed for different crops.

For improved secondary separation and higher throughput, the centre risers of the straw walkers have been redesigned for extra loosening of the crop and achieve faster transfer to the subsequent straw walker racks.

In addition to the anti-blockage system on the drum, there is new sensor-based monitoring of the straw walker crop flow. If blockages start to develop, then the operator receives acoustic and visible warnings. An optional Cemos Auto Crop Flow feature automatically deactivates the header and feeder if a risk of blockage or serious belt slippage is detected, to prevent more crop being taken in.

Enhanced cleaning

The upper and lower sieves move in opposite directions and have a total 4.8m2 sieve area. The sieve design is enhanced in line with Lexion and Trion cleaning systems. Electric sieve adjustment and loss monitoring is standard. The radial cleaning fan is adjusted from the cab and can be controlled automatically for uphill and downhill working with the optional Auto Slope. The optional 3D cleaning system compensates for lateral tilt to 20% on slopes.

Grain tank capacity

Grain tank capacity is 5,600 litres for the Evion 410 and 6,500 litres for the Evion 430. Unloading at 90 litres per second increases productivity when emptying stationary on headlands. The 105-degree tube movement means trailer filling progress is easily monitored from the seat. A pivoting end spout is an option.

Dynamic Power

The Cummins 6.7-litre engine is like that used in the Trion, and maximum power is available at only 1,900rpm. Dynamic Power Management delivers only the necessary power by ‘repositioning’ the engine’s power band and achieving significant fuel savings up to 10%.

The ground-drive transmission is hydrostatic with manual control and there are three mechanical gears.

Header choice

The Evion has a similar header mount to Lexion and Trion models so a wide range of attachments is available. Maximum cereal header width is 6.8m.

Contour ground adaptation automatically adapts the attachment to compensate for ground undulations parallel to the direction of travel. Auto Contour, programmed through the Cemis 700 terminal is an option, and allows the cutterbar to adapt to both parallel and transverse ground undulations.

Operator environment

The spacious cab has similar controls to larger combines, including the CMotion joystick. There is a large, clearly arranged keypad and a Cemis 700 touchscreen. Pre-programmed settings for a range of crops provide a reliable start point, and these can be optimised for the conditions during work and saved for recall later. The Cemis 700 terminal is fully Isobus compatible and can be removed for use in tractors and with other implements.

Automatic climate control is standard, and footrests and a cool box are options. LED lighting is also included, but optional upgrade kits are available.

Claas UK combine product specialist Rob Portman told Farmers Guide that most demand for the new Evion series will be from farms with 20–200ha which prefer operating new and more efficient combines with a comfortable cab, features and a choice of headers similar to the latest larger models.

Forage range grows

Claas has added the Disco 9700 RC Auto Swather to its line-up. The mower-conditioner with a belt merger is specially designed to provide high work rates even in very high yielding, bulky but fragile crops such as wholecrop rye and triticale.

The infinitely adjustable working width is from 8.8–9.5m, and both mower units can be drawn in to increase overlap and avoid misses on field headlands and cross-slopes, or pushed right out for maximum productivity – utilising the full 9.5m working width.

The roller-conditioner crushes the crop gently without seedhead losses which would result from a tine conditioning action. The counter-rotating rollers drive through a heavy-duty driveline including a specially developed scissor gearbox to ensure the heaviest crops are pulled through without blocking. The conditioner spans the full width of the mower bed for efficient crop transfer, then the forage is discharged uniformly onto the wide belts of the Auto Swather to create a perfectly shaped swath.

In demand from professional contractors

The grouper belts are 1.1m wide with Kevlar reinforcement to handle heavy and bulky crops. The grouper units are individually controlled and when working without swath grouping, with less regrowth or when less wilting is required, one or both belt units can be folded up hydraulically to consolidate a working width of 19m to 12m for the next pass with a 12.7m four-rotor swather.

The new Disco 9700 RC Auto Swather is rated for tractors up to 500hp, and it was tested last year in a crop of wholecrop Triticale yielding 60t/ha in Texas, where it performed well at speeds of 15–20kph.

Claas UK forage product specialist, Dean Cottey said that most demand for the new mower will be from professional contractors harvesting a range of crops including high volume biomass, wholecrop rye or triticale as well as grass.

The New Holland Agriculture CH7.70 combine is the latest addition to the CR twin rotor rotary ‘proven record-holding’ range and the proven CX conventional range.

This crossover combine delivers outstanding grain and straw quality for all crops and conditions. The highly fuel-efficient engine with patented HI-eSCR 2 technology for Stage V compliance delivers high productivity, extremely low operating costs and comes with the superior comfort of the Harvest Suite deluxe cab. 

Threshing adaptation to match the conditions

The crossover technology delivers up to 25% higher throughput than a conventional combine in this segment. The two-drum threshing system features a 600mm diameter drum delivering outstanding threshing performance. The large drum combined with the user-friendly sectional concave, enables fast adaptation to different crops, in less than 20 minutes.

Drum speed is controlled from the cab by a new heavy-duty hydraulic drum variator. This ensures that the speed is perfectly matched to crop and field conditions. The New Holland Opti-Thresh system adapts to crop conditions and maturity by repositioning the rear part of the concave – no tools required. When the hinged top section is moved away from the drum, the rubbing action is gentler, improving straw quality.

The CH7.70 combines this high-capacity two-drum system with New Holland’s proven twin rotor concept, delivering the Crossover Harvesting experience. The specially designed 21-inch, 3.45 metre-long twin rotor system provides the largest separation area in the segment, at some 2.9m². When switching between crops, the changes required are minimal, resulting in outstanding crop-to-crop versatility.

Designed and developed at sister company Kverneland Group’s baler competence centre in Ravenna, Italy, the FB1000 uses two bale chambers arranged in series, to allow a number of rollers to be shared.

Operating as a pre-chamber, the front half of the FB1000 produces two-thirds of the bale. As the pre-chamber reaches its preset density, crop flow is diverted into the main bale chamber, allowing baling to continue non-stop. The pre-chamber is then opened, moving the pre-formed bale into the main chamber, where it can be taken up to its maximum size of 1.25m.

Once bale formation is complete, crop flow is switched back to the pre-chamber without stopping, allowing round baling to continue as a non-stop process. Net is then applied to the completed bale in the main chamber, after which the tailgate is opened and the finished bale is transferred onto the wrapper. This entire sequence enables baling to continue uninterrupted.

To make bale transfer simple, reliable and fuss-free, the FB1000 uses a wrapper frame mounted on a parallel linkage. This enables the wrapper to be lowered from its working position to collect the completed bale as it rolls from the main chamber. This avoids the need for a complex mechanical transfer system.

With the bale collected, the wrapper is raised to allow twin satellite arms to rotate around the bale. Unlike traditional wrapping mechanisms, the FB1000’s twin satellite arms rotate in a vertical plane. With the required number of film layers applied and the satellite arms in their parked position, the wrapper frame is lowered to allow the rear wrapper roller to be raised, gently releasing the wrapped bale onto the ground.

An ISOBUS-compatible machine, the FB1000 is operated through an IsoMatch Tellus PRO terminal, offering fully automatic control of the baling and wrapping processes, along with manual override functions to suit changes in field topography.

Up front, the FB1000 is equipped with a 2m grass pickup with dual cam tracks, feeding crop through an 800mm diameter intake rotor. Overall baler length is kept short for transport by folding the wrapping table vertically behind the main bale chamber.

Operators can choose from a combination of 6, 12, 13 or 25 knives through the Super Cut crop chopping system. Knives benefit from spring-loaded protection, and the FB1000 includes a drop floor mechanism.

The Ziegler 4WT header makes attaching and removing the large header quick and convenient.

Based near Saffron Walden in Essex, Abrey Agricultural is the official UK importer for Ziegler products. The German manufacturer offers a range of high-quality header trailers and specialist combine headers – including versions for oilseed rape, sunflower and maize harvesting. The header trailer line-up includes single-axle models suitable for headers up to 7.7m working width and weighing up to 3.6t. Close-coupled, tandem-axle trailers can carry headers up to 9.5m and weighing up to 3.6t, and double-axle trailers with a steering front axle and a fixed rear axle will accommodate headers up to 10.7m and weighing up to 6t.

Exceptional manoeuvrability

While UK sales of all the trailers are increasing, the Abrey team has experienced a significant rise in the numbers of enquiries and sales of its flagship Four Wheel Turn (4WT) trailers. These transport headers up to 12.5m and with weights up to 6t or 7.2t depending on their construction, but the biggest attraction for users is their ability to accurately follow the same line as the tractor wheels when manoeuvring, making it easy to turn into tight field gateways from narrow lanes – typical on many UK farms.

Premium products

Abrey Agricultural managing director, Toby Abrey commented that he feels fortunate to have such a great range of products to offer, and highlighted features which  make the 4WT trailers so popular.

These include:

• V-Lock system for easy attachment and securing of the header to the trailer
• Main frame painted to match the combine brand colour – powder coated and oven-baked
• Galvanised supports keep the trailer looking new – for enhanced residual value
• Accurate following and turning into gateways whether behind the combine or a tractor
• Standard tyres 260/75-15, but with options up to 22-ply
• Heavy-duty, 10t-rated axles
• Heavy-duty, twin-beam construction available on 40, 45 and 50ft header trailers
• 40mm/50mm drawbar eye options
• Overrun braking (so trailer always brakes effectively whether behind the combine or a tractor)
• Back-up from the official UK importer – spare parts readily available.

Agco dealer view

Main Agco dealer, Chandlers Agricultural recommends Ziegler headers – especially to customers operating Ideal combines with the widest SuperFlow or Geringhoff headers. “We don’t use any other brand now,” explained Chandlers’ harvesting dealer principal, Sean Stanfield. “When we assemble the trailers after shipping, everything fits perfectly, and they are incredibly well made.

“Customers love them, and they tow like a train. We use a Ziegler 4WT trailer to transport our demonstration combine headers and, often when we turn up on a farm, the first thing customers comment on is the way the header trailer negotiates turns. Headers lift on and off easily and lining them up is never a problem.”

Sean said that Ziegler has also developed a version of the trailer to transport heavier flex Draper headers. “Since last year, we have been able to supply Geringhoff Flex headers as an approved option for Agco Ideal combines, and our demonstration machine was very busy last harvest. The Geringhoff header, with its ability to flex, requires extra support for transport and it’s heavier, but the specially designed Ziegler trailer makes it as easy to move about as a conventional header.

“The back-up from Ziegler and the Abrey team is always excellent, so the trailers are an obvious choice.”

James Nott says the Ziegler 4WT trailer is well made and makes it easy to move his 45ft John Deere header between harvesting locations.

Essex-based farmer’s experience

Essex-based farmer, James Nott farms near Clare, and he replaced two John Deere combines with 35ft headers, with a single John Deere X9-1100 with a 45ft header, just before the 2021 harvest. He chose a Ziegler trailer.

“I have always got on well with Toby Abrey and the rest of the Abrey Agricultural team,” he said. “I used two different brand header trailers with my previous combines, but the Ziegler 4WT trailer was the obvious choice for the new, wider 45ft header.

“Ziegler’s build quality is very good – better than any other brands I have tried, and the trailer does just what it was bought to do. It turns easily through narrow gateways and the wheels follow the path of the tractor precisely. There have been occasions when I have watched it enter a field and doubted whether it could make the turn, but then it just does – it’s very successful.”

Trailer success led to header purchase

In recent years, James has diversified into growing grain maize. A small area was grown as a trial for the 2021 harvest, more was grown successfully last year and now an even larger area has been planted for the 2023 harvest. A conventional combine equipped with a specialist maize header harvests the grain and, after becoming convinced of the crop’s benefits, James ordered his own 12-row Ziegler header for his John Deere X9 combine from Abrey Agricultural through his local John Deere dealer, Tuckwells.

Several brands were considered before James ordered the Ziegler. “I’ve been very impressed by the build quality and performance of the Ziegler trailer, and I know that the Abrey team will provide excellent back-up, so buying a Ziegler header through Tuckwells, which also supplies and looks after our combines seemed the obvious choice.”

Recommends Ziegler

Tuckwells group sales combine specialist, Steve Bucket said that he always recommends Ziegler trailers to customers. “Toby and the rest of the Abrey team are very easy to deal with and the Ziegler trailer is so good,” he stressed. “We’ve seen a big increase in numbers of four wheel-steer trailers sold recently as this sort of arrangement is essential for moving flex headers over 30ft cutting width on the road.” FG

Strautmann Magnon 8 CFS 370 with hydraulically moving front wall.

Unlike its larger sibling, the Magnon 8 is a compact machine with a loading capacity of 36m³ to 44m³ (DIN) and a smaller ‘external’ footprint to other wagons with similar DIN. Its three models (370, 410 and 450) are aimed at agricultural businesses and contractors with high demands who are in need of compact dimensions.

New features in the Magnon 8 series include a hydraulically moving front wall, which provides the wagon with increased capacity.

As the machine starts filling, the front wall is in a vertical position towards the rear of the wagon, but when the build-up of chopped grass pushes against the tailgate sensor, the front panel moves forward in three stages to increase capacity by up to 4.5 m³. This mechanism ensures maximum density is achieved throughout the loading operation.

In addition, when discharging, the front wall is hydraulically moved to the rear of the machine to assist with unloading.

Alongside standard Flex-Load pick-up and Exact Cut, all Strautmann forage wagons benefit from the Continuous Flow System (CFS) pick-up unit which ensures excellent loading while keeping power requirements low. According to the manufacturer, all CFS units provide good adaptation to ground contours, long service life and extremely easy tine change.

Moreover, the extra-wide (2.25m) CFS pick up of the Magnon 8 ensures a wide swath of grass can be collected, which is particularly useful around corners. It also means the outer edge of the rotor is kept full of forage to even out loading across the full width of the rotor.

To preserve the drive line and maximise torque, the high (1000rpm) speed through the drive line is reduced to the rotor, which is powered via an oil-bath gearbox.

New double-roller crop press with mechanically powered Flex-Load pick-up for improved material flow.

In addition, the wagon’s crop press roller has been completely redesigned to optimise forage flow into the Flex-Load pick-up, with the new double roller being larger in diameter and featuring a slip-proof profile. What’s more, a guide roller mounted behind the pick-up is available as an optional extra for optimum adaptation to the ground.

With 44 knives and a theoretical cutting length of 35mm, the Exact-Cut cutting unit guarantees chop quality and consistency, the manufacturer said. Due to a rapid-trigger protection function, the double-sided knives are automatically retracted from the conveying unit if, for example, a foreign object is detected.

The retracted knife then automatically returns to its working position, helping to keep maintenance to a minimum.

The forage box on the Magnon 8 is 2.25m wide and consists of four round steel chains (10 x 31 mm) embedded in the steel platform floor, which is entirely powder-coated for protection against corrosion. Each chain has a breaking strain of 13t.

While a boogie tandem chassis is standard on the two smaller Magnon 8 models (370 and 410), the 450 model comes with a hydraulic tandem chassis that is an optional extra for the two smaller models.

All Magnon 8 wagons come with 4 x 710/50 R26.5 wheels as standard, however, the hydraulic tandem chassis can be fitted with wheels up to 800/45 R 30.5, enabling 30.5″ tyres. As larger wheels offer increased stability, these are ideal for operating on sloping ground.

A tridem chassis with an axle load of 27t, electronic active steering and lifting axle is also offered as an option on the larger 450 model.

Last but not least, the Strautmann ISOBUS control with its intuitive menu navigation and various automatic functions is included as standard. For maintenance work, the drawbar and the cutting unit can be conveniently operated from the outside. If the tractor is not ISOBUS-compatible, a 5.7″ control terminal can also be delivered as an optional extra

The new lateral console has simplified operation – it is ergonomically designed for easier identification of all main functions and settings. Mirroring the arrangement found on the latest Case IH 150 series Axial-Flow combines, the console also now incorporates the AFS Pro 700 touchscreen operating terminal, via which all machine settings can be made and operating data monitored.

AFS Pro 700 provides fingertip setting and operation of all key functions, such as reel, knife and rotor. It also provides the information formerly shown on the A-pillar displays, putting data such as fuel level and engine temperature in the driver’s eye-line when observing the header – resulting in a clear view of the cutterbar and reduced operator strain, with all information grouped together for assessment at a glance.

Integration makes operation even easier for the operator, with no need to stretch in the seat, according to Case. The armrest incorporates a new joystick, designed, like the console, for intuitive operation.

Integrated into the joystick is a new electro-hydraulic unloading auger engagement switch, upgraded from manual engagement for easier, smoother, simpler unloading of the grain tank.

Electronic actuation responses have been enhanced with the fitment of a new universal communications module, for faster reactions and more accurate control of key electronically-controlled functions.

“The 4000 Exclusive series Axial-Flow combines have a strong following among users seeking simplicity of operation alongside simplicity of design and maintenance,” says Massimiliano Sala, EMEA Region product manager, Case IH combines.

“With these latest updates, those characteristics remain, but customers will benefit from even easier operation and reduced operator fatigue.”

The post Combine range gets significant operating upgrades for 2023 appeared first on Farmers Guide.

For the 2023 season, global farm equipment supplier AVR is planning a major upgrade of the actuation method of the All Conditions Control (ACC) digging unit’s depth control mechanism. With the ACC digging unit, users can harvest either using diabolos or probes, without exerting any pressure on the ridge.

Following thorough review, the control technology responsible for depth control when harvesting using probes is now a lot more accurate. This means the digging unit, and as a consequence the whole machine, can be operated with more stability than ever.

Immediate advantages for the user include:

• More comfort for the driver: the control performs very well under all circumstances (e.g. in case of spray tracks, on inclined terrains etc.), making manual intervention no longer necessary
• More precise control also improves harvesting quality. A potato harvester’s performance is largely determined by the accuracy of the harvesting depth. Harvesting should not be too deep or too shallow, and the less soil enters the harvester, the less processing is required. This reduces the load on the machine, resulting in a higher harvesting speed, less wear and a lower fuel consumption per hectare
• At higher speeds, the control – and as a consequence the whole machine – remains remarkably stable.

All of these advantages are offered by the AVR Comfort Drive, found in the new Puma 4.0. Meanwhile, each Puma is also equipped with the necessary modules for machine connectivity, including AVR Connect.

AVR Connect is an online reporting tool for all machine activities and a repository for both on- and off-field machine data. AVR Connect makes more data available to users, enabling a more effective use of machines and resources. Users can also monitor machines remotely, and there are options for remote diagnosis.

What’s more, AVR offers an optional Trimble NAV900 GPS sphere ex-factory, including a one-year RTX precision subscription. Precision GPS is a must for accurately collecting data, such as yield measurement at the Puma’s picking-off table.

Lastly, at a time when fuel prices remain record high, Puma’s fuel consumption is very low owing to its efficient Volvo engine, sophisticated hydraulic system, lightweight construction and large tire sizes.

This is especially the case when harvesting occurs at slower speeds, such as 1,250 rpm. For example, based on data from all connected Puma 4.0s, the average consumption per engine hour (not just harvesting hours) was 27.6-litres/hr for the 2022 harvesting season.

Hertfordshire-based Fox Feeds Ltd invested in a New Holland Forage Cruiser 550 from Ernest Doe to harvest grass and lucerne for its range of quality equine feeds.

Hertfordshire-based Fox Feeds Ltd has been trading since 1982 and specialises in the preparation and supply of forages and fibre-based feeds, supplied predominantly to the equine market. The company started supplying haylage which had been bagged and fermented, but in 2000 a drier was installed to rapidly reduce the moisture content to 10% after which the forage is supplied immediately as a feed constituent to other feed manufacturers or stored and then sold.

Ideal break crops

The forage is mainly from lucerne and grass. The lucerne is grown in three- to four-year leys within arable rotations. “It’s an ideal arrangement,” explained operations manager Freddie Barclay.  “We have an agreement through which crops are grown and managed by landowners according to our instructions to ensure the quality we need, then we do the harvesting with our own staff  and machinery.

“Including the forage leys within arable rotations is very good for the soil, and it introduces very competitive plants which help reduce weed burdens, and with deep roots which contribute to a healthy soil structure.”

Specialist machinery

The forage is cut using tractor-mounted triple mowers, or a MacDon M1170 swather if the crop is particularly difficult to cut, then swaths are created using a rake or belt merger. The forage harvester picks up, chops and loads the forage into trailers for transport to the drying facility.

“For us, the priority is harvesting forage in optimum condition then drying it as soon as possible to preserve the quality, so operating our own forage harvester is the best way to ensure we can do that,” explained Freddie. “There aren’t very many contractors with forage harvesters in our area, and even if there were then they wouldn’t be interested in coming in to cut small areas at a time during limited weather windows, or when  we have the capacity to dry it.”

Service led to brand change

Initially self-loading forage harvesters with integrated bodies were used then, 16 years ago, there was a change to conventional self-propelled models purchased through a local main dealer.  “We remained loyal to one brand and owned three similar machines in succession,” said Freddie. “The dealer looked after us well and also supplied our tractors, and we didn’t feel any pressure to change brands.

“However, we have increased the amount of business we do with the Ernest Doe & Sons Ltd Braintree depot in recent years – including hiring fleets of six New Holland tractors for the harvesting season. The team looks after us well, so when the forage harvester was due for updating this time, we were happy to consider the New Holland Forage Cruiser instead. We accepted the offer of a demonstration during harvest 2020, and it performed very well.”

Immediate improvement

Although the chop quality of the previous harvesters was generally good, long, uncut strands were a frustration when conditions were dry. “The staggered blade layout included a gap and when the crop was especially dry there were a lot of uncut stalks. The New Holland rotor has blades right across, and we noticed an immediate improvement when we trialled it.”

The farm’s own new FR550 harvester was delivered for the start of the 2022 cutting season. “It’s easy to drive. The cab is comfortable, and the visibility all around is excellent,” said Freddie. “Lucerne can be very sticky in warm weather, and although we haven’t had any blockages so far, we had a second water jet installed by the Ernest Doe team just to help maintain an efficient flow.”

Plenty of torque

Even though the harvester is only the second model in the New Holland line-up, there is plenty of torque allowing fuel efficient operation in Eco mode. This means that the engine runs slower – at the bottom end of its flat torque curve – saving fuel and reducing noise. There is no reduction in chop quality, as the chop length and rotor speed remain constant, and when dense or uneven swaths create challenging conditions, then maximum power is available immediately at the touch of a dashboard-mounted button.

Freddie said that the New Holland’s Power Cruise mode helps achieve high work rates. “I set what I think is a reasonable working speed for the conditions, then activate Power Cruise mode and the harvester immediately speeds up by another 2kph or so. The travel speed is managed to maintain a constant chopping load, and it reduces to avoid the risk of blockages when needed. “It’s used a lot when harvesting grass as the chopper is always kept full, and that is what’s needed to maintain optimum chop quality.”

Quick, simple maintenance

Comparing the New Holland’s fuel consumption to the previous machines is difficult as no two seasons are the same, explained Freddie – but he said it seems very reasonable. Daily maintenance and checks are quickly and easily carried out, and with optional auto-lube fitted there are only four, 10-hour grease nipples and 10 which require lubrication every 50 hours. The harvester is blown clean every day to prevent dust build-up.

Options specified included LED lights which Freddie describes as very worthwhile, undercover servicing lights and an air blow-down kit which provides air hose connectors for maintenance and cleaning around the machine.

Back-up as good as expected

“It was a big leap of faith changing from a brand of forage harvester and a dealer we had known for so long, to the New Holland supported by Ernest Doe,” continued Freddie. “We had experience of Ernest Doe’s excellent customer service through hiring the tractors, and when we purchased a MacDon swather last year, but  it was still a big change for us.

“However, as we had hoped, the back-up has been brilliant. We received training at New Holland’s UK headquarters, and then members of the manufacturer and dealer teams were on-hand to help set the harvester up in the field for its first use. Within just a few hours of starting work I felt completely at home on the machine, and for anyone who has used a forager before, the New Holland controls make operation very simple. We have worked 345 engine hours since it arrived, without losing a single day due to technical issues or breakdowns.”

“Dealer values our business”

Freddie describes dealing with the Ernest Doe team as very easy. “We feel valued as customers and are well looked after. I particularly like the WhatsApp-based customer care system. If I have a query or a fault occurs, then I just send a message to the Ernest Doe WhatsApp group, and it’s read by both the sales and service teams. That means that everyone is aware when someone responds to my query, and everyone is also aware if there has been no response. In that case, even those who wouldn’t usually get involved will step in to try to find a solution. It’s a good system that works well.”

Area sales manager, Mark Jolley, added: “The New Holland Forage Cruiser 550 is ideal for Fox Feeds. Ernest Doe is well known for its customer service and back-up for tractor and combine owners, and we have invested to ensure we can look after forage harvester users equally well.”

Chop quality, cost and back-up

“Our main priorities for a forage harvester are performance, cost, and back-up, and the New Holland satisfies all three. We will probably keep it for four to five years before it’s updated and, as long as the cost is reasonable, then it’s likely we will opt for a similar machine again. For us, being able to harvest at the right time to achieve the right quality is far more important than high work rates, and the 544hp Forage Cruiser 550 gives us the chop quality we need, and it’s backed by the brilliant Ernest Doe team,” Freddie concluded.

There are five new 700 Vario models, from 203hp to more than 300hp, and the series meets growing demand for extremely versatile tractors capable of heavy draft work and demanding transport applications, but which are also light enough for top-work, and tasks such as spray and fertiliser applications. The new models will be offered alongside the existing 6th generation 700 Vario line-up, and deliveries commence next year.

Longer wheelbase

The new models feature a 2,900mm wheelbase – significantly longer than the current 700 Vario series. This results in an even better ride, greater lift capacity and improved ability to transfer power to the ground. Despite the long wheelbase the new tractors have an incredibly tight turning radius for their size – and match the manoeuvrability of the smaller 500 Vario models. They can be supplied with a 60in track width and narrow dual wheels – for specialist row crop applications. Tyres up to 2.05m diameter can be fitted – increased from 1.95m on existing 700 Vario models. On the 726 Vario and 728 Vario, 650/85R38 rear tyres are standard and 650/65R42 tyres are an option. Fendt 720 Vario, 722 Vario and 724 Vario models feature the smaller size as standard.

The new 700 Vario models have a completely new AgcoPower engine and a concentric cooling system.

Impressive power for size

The engine and transmission are both brand new. It is the first time that Fendt has introduced a previously unused engine and gearbox simultaneously on the same tractor.

There are five models – from 203hp (rated) to 303hp with boost, all with a new version of Fendt’s VarioDrive transmission.

Despite the long wheelbase, the tractors boast extremely compact dimensions and an impressive 30.5kg/hp power-to-weight ratio, making them particularly manoeuvrable and minimising ground pressure and compaction. Ideal weight distribution can be achieved, with ballast added front and rear up to a maximum gross vehicle weight of 15t.

Peter Settele says that to get the best performance and economy from the new tractors, users must be familiar with the low engine speed operating concept.

New engines

The new AgcoPower 7.5-litre engines have six cylinders with four valves per cylinder and an electronically controlled turbo charger. Fendt’s proven iD low engine speed concept combines impressive productivity with miserly fuel consumption. The transmission, hydraulics and cooling system have been designed to make best use of the torque available without requiring high engine speeds. The engine idles at 700rpm, and rated power is at 1,700rpm – down from 2,100rpm on sixth generation models. Max torque is at only 1,300rpm, and the engine achieves maximum fuel efficiency across an exceptionally wide 1,200–1,700rpm speed range. With almost constant torque available between 1,150–1,500rpm, this means that the ‘sweet spot’ for operation is between 1,400–1,500rpm where near maximum power and torque are produced simultaneously.

“To get the best from the tractor, the operator has to bear in mind the low engine speed concept,” explained Fendt tractor product specialist Peter Settele. “There is no advantage to running the engine at high revs. The economy PTO setting achieves the rated output speed at 1,300rpm rather than the standard 1,650rpm, but I would only use it for implements with an extremely low power requirement, or when implements are too small for the tractor. Otherwise, there is no real benefit in terms of reducing the fuel consumption as the engine achieves maximum efficiency across the standard working speed range.”

Intelligent boost

Fendt Dynamic Performance, standard on the 728 Vario, provides the extra 20hp boost only when it is needed, but it is always available even for stationary working applications. The power demands of ancillary systems such as the cooling fan, air conditioning, lights, PTO, hydraulic pump and transmission are constantly monitored, and the engine output is uprated to compensate so that power available for the main task remains constant.

Efficient cooling

Rather than sucking air through the cooling packs, Fendt’s Concentric system pushes it through using a hydraulic-driven fan. Because the air is at ambient temperature and denser than air already warmed by the cooling packs, the system requires a lower air volume than traditional systems – reducing the fan power requirement by up to 40%. The fan speed is independent of the engine revs, and the cooling system can respond quickly if any cooling circuits require extra air flow, and the vacuum created by the fan is used to extract dust from the primary air cleaner, reducing the cleaning requirement. An automatic reversing fan is an option – helping keep the cooling packs clear of dust and debris.

The surface below the cooling packs is flat, and with no fan between, they are easily cleaned by washing or blowing out. “If it’s easy then people will do it,” stressed Peter. “Clean coolers mean improved fuel consumption as less cooling power is needed.”

An additional advantage of the Concentric fan layout is that it allows a wasp waist and a narrow engine hood, and the new 700 Vario tractors benefit from a tight 52-degree steering angle and a forward  view that wouldn’t be possible  with a more traditional cooling system layout.

The FendtONE control concept is standard.

New transmission

Fendt’s VarioDrive transmission concept was first used on the flagship 1000 Vario series, and the latest 900 Vario models have it too. Now, a smaller version (TA190) has been developed for the seventh generation 700 Vario series tractors.

Unlike conventional four-wheel drive systems, VarioDrive distributes torque to the front and rear axles dynamically. A single hydraulic pump powers two drive motors. One delivers uninterrupted torque through a hydro-mechanical drive to the rear axle and the other drives the front axle. An intelligent clutch distributes the torque to the axle with most traction to maximise pulling performance.

On the road, and at speeds over 25kph, the front axle drive disengages completely to reduce drag and fuel consumption.

Additional advantages of VarioDrive include pull-in-turn which increases efficiency during tight turns. Because the front and rear axles are driven independently, the system can increase the speed of the front wheels so that they pull the front of the tractor towards the steering direction. This results in an incredibly tight turning radius – demonstrated at the event by negotiating a challenging obstacle course alongside a much smaller  500 Vario model.

VarioDrive has only one operating mode and is fully automatic. On standard Vario models, users select the field or transport speed range, but this isn’t needed on the new system, and four-wheel drive is always available and engages when it will offer an advantage. During transport tasks, the system improves efficiency and safety, including when pulling away from junctions when four-wheel drive cuts in maximising traction and acceleration.

Safe transport

High-speed safety is provided by dual-circuit brakes. Fendt Reaction Steering, and a brake light and deceleration assistant. Fendt Stability Control reduces side lean at speeds above 25kph and minimises roll – also increasing operator comfort.

A new trailer braking assistant is an option. Sensors measure the thrust of the trailer and, when travelling downhill, if the trailer is pushing hard then the trailer’s pneumatic brakes are automatically activated. Trailer Brake Assist will be available from late 2023.

Hydraulic performance

Hydraulic oil flow of 165 litres/min is standard and a 220 litres/min system, with a variable displacement pump and electronic load sensing, is an option for Profi and Profi plus versions.

The new tractors are compatible with future versions of Tractor Implement Management (TIM) expected in the next few years. Extra functionality includes flow rate adjustment by the implement, increasing work rates and improving fuel economy.

Eighty litres of oil can be removed, and the tractors can have up to five valves at the rear, two at the front, plus an additional three in the middle. A new control block can be specified below the cab to supply a loader – avoiding the need to sacrifice a valve elsewhere.

Use flat-face couplings

Peter pointed out that the new tractors were all displayed with flat-face hydraulic couplings. He stressed that these should be in use on all modern farms and machinery, as they offer higher flow rates than push-in connectors, while also avoiding oil leaks and the need for messy oil containers. They are easily wiped clean and reduce oil contamination.

Cab upgrades

The VisioPlus cab has an uprated frame but looks similar to the existing version. The glass area is the same as before – offering exceptional all-around vision, especially to the front for high-level loader work where the popular curved windscreen provides a 77-degree viewing angle. A side wiper on the right-hand window maintains a clear view in wet or  dusty conditions. Two optional cameras can be specified, as well as two bonnet-mounted work lights.

Operator comfort is even better than before. An increased range of six seats includes a new top-specification Isri version – with electric position adjustment plus four-way lumbar support and adjustable side bolsters, a massage function as well as heating and cooling. Seat adjustments can be made from the VarioTerminal, and users can save their preferred position and settings in the user-profile memory and re-select them with one touch of the screen.

The air conditioning system provides 30% extra cooling capacity, and an effective fridge cools drinks and food.

The updated Fendt cabs can be equipped with Cat 4 filtration for increased safety for spray applications. In its basic form, it provides protection to Cat 2 standards. Cat 4 filtration will be available from late 2023.

FendtONE

The FendtONE operating concept is standard. Control is by the multifunction joystick and optional 3L joystick. A 10in dashboard display, plus a 12in VarioTerminal on the armrest are standard, and an additional roof-mounted 12in VarioTerminal is an option.

New Cargo 6.100 loaders are especially designed to suit the powerful Fendt 700 Vario tractors.

New loaders

Many 700 Vario-series tractors will be supplied with front loaders, and new Cargo and Cargo Pro 6.100 versions with a wider frame, extra strength and an upgraded mounting system have been added to the line-up. “These are designed to withstand the extra power and torque from tractors up to 300hp,” continued Peter. Maximum lift height is 4,850mm (4,460mm previously), and maximum lift capacity is 4,470daN.

Pro versions add a weighing function, and maintenance requirements based on working hours are monitored through the VarioTerminal.

Control through the optional 3L joystick allows up to three functions to operate simultaneously.

A new multi-coupler with an automatic closing cover prevents dirt ingress when the loader is removed.

FendtONE allowed the GPS guidance and field map to be displayed on the dashboard – making it easy to view while working.

Test-drive

Farmers Guide tried the new  flagship 728 Vario handling loose materials with the new Cargo 6.100 front loader, and cultivating stubble with a Lemken Karat 10, 5m  heavy cultivator.

The benefits of VarioDrive transmission were immediately obvious. For loading, the manoeuvrability is exceptional for a tractor of this size as the front wheel drive engages to pull the tractor around. With no fixed ratio between the front and rear wheels, the steering is light and there is little scrubbing – which will result in a longer tyre life particularly for yard-based operations on hard surfaces.

Cultivating deep in the hard, dry conditions tested the tractor’s power and traction capabilities. During each headland turn, and when working around curves on the field headlands the steering action was always positive with little sign of front wheel slip, and although the pull-in-turn VarioDrive action is subtle and progressive it was obvious that the front wheels were doing more than just steering.

The transmission is always progressive and smooth, and  there is very little operating noise.  The drive engages without any  delay, and precise movements are easily achieved.

Roland Scmidt says the new seventh generation 700 Vario tractors offer excellent versatility for year-around use.

All-around vision is very good. With the new loader fully raised there is a good view of the attachment, and the narrow bonnet gives a clear view of the front wheels. For the cultivating demonstration, the seat was swivelled to the right, and it was easy to watch the front of the tractor during headland turns, while also monitoring the implement. The FendtONE displays are clear and easy to view, even in bright, sunny conditions.

The test tractor had the new  Isri seat, and it was easy to achieve  a comfortable working position.  It provides plenty of support, and  on uneven ground at higher speeds, the combination of the axle, cab and seat suspension ensures a comfortable ride.

The cultivating demonstration proved the benefits of Fendt’s iD low engine speed concept. Pulling the 5m cultivator at 11.3kph, the engine speed settled at approximately 1,450rpm. The conditions were exceptionally tough, but spot fuel consumption under full load was  only 50–52 litres per hour.

Attractive new  option for buyers

“Priorities for UK buyers include total cost of ownership,” explained Fendt vice president marketing, Roland Schmidt. “The new Fendt 700 Vario tractors will hold their value well, and we trialled them against all their main competitors in the field and on the road, and our arguments in terms of fuel consumption are convincing.

“We offer attractive extended warranty packages allowing customers to guarantee their ownership costs per hectare too.”

Roland said that the new tractors bridge the gap between the current sixth-generation 700 Vario series, and larger 800 Vario and 900 Vario models. “The compact size and excellent manoeuvrability make them extremely versatile, and suitable for year-around use,” he added. “All tractors are a compromise, but our new 700 Vario series is an extremely attractive option for all sorts of applications. UK dealers are very excited by the new models and believe that they will provide additional sales opportunities.”

Katana 850

Fendt has entered the 800hp-plus forage harvester market with its new flagship Katana 850. David Williams saw it prove its capabilities in an impressively heavy maize crop.

The Katana 850 has a new Liebherr 6-cyl, 18-litre engine developing 847hp, which replaces the V12 MTU power unit of the previous most powerful Katana 85. The new engine meets stage 5 emissions standards using SCR (AdBlue) only, without a DPF or EGR.

The Katana operates at full capacity with the engine speed at 1,800rpm, or for harvesting lighter crops an Eco mode can be selected. This maintains the standard 1,150rpm drum speed, but reduces the engine revs to 1,500rpm, saving fuel. The engine is mounted longitudinally within the Katana’s chassis, with a low centre of gravity for maxim stability.

“The engine is more efficient  than the previous Katana 85, and lighter too,” explained Fendt UK  forage harvester product specialist Dan Woodward.

An optional reversing fan with adjustable blade pitch adjusts the cooling performance to suit the conditions. The automatic reversing function can be set to operate each time the engine revs reduce – keeping the cooling pack clear of debris while leaving the operator free to concentrate on the harvesting process.

The Katana 850 equipped with a Kemper 12-row header performed well in the extremely heavy maize crop.

Optimised crop flow

The Katana’s crop feed system achieves a uniform flow through the machine. A new 12-row Kemper 490-plus maize header is available to fully utilise the harvester’s performance and optimise work rates. The header is suspended on the Katana’s pendulum mounting frame which allows it to pivot up to 14 degrees in either direction to optimise ground-following capability.

The header speed can be fixed or set to adjust automatically.

From the header, the crop passes through six pre-compression rollers in the feed intake. These compress the crop and hold it securely as it enters the drum, ensuring consistent chop length. Metal and stone detectors in the first feed rollers, 920mm in front of the drum, allow plenty of time to stop the flow and prevent damage.

The Katana’s chopping drum is the industry’s largest at 720mm diameter, and it can be fitted with 20, 28 or 40 knives for a chop length from 2.6–41.4mm. The knife sharpening system continually adjusts the stone during use, so that the entire blade width is sharpened gently and evenly. This maintains optimal chopping performance and maximises the blade working life. The blades are mounted on slotted holes and can be repositioned so that the entire length is utilised.

Chop length is controlled by the rotation speed of the six feed rollers, through a gearbox with two speed ranges and a hydraulic drive with two virtual ranges.

Fendt’s range of 300mm diameter crackers includes an R version with a sawtooth profile, and the RS with a V spiral groove. Speed differentials of 30 and 40% are available.

A manual winding system moves the cracker in and out of its working position.

Control appearance and layout is similar to Fendt tractors.

Crop handling

The revised discharge chute has a 210-degree swivel angle and a maximum loading height of 6.2m making it suitable for use with the largest trailers. Optional Fendt Fill Control automatically adjusts the discharge flap as the chute rotates, so that forage is delivered to the same central point across the trailer. A chute-mounted camera provides  a clear view of the crop entering  the trailer.

Crop nutrient sensing is available through the optional IT-Photonics NIR sensor. Connection is through Isobus and, as well as monitoring crop quality, it also measures crop flow and provides yield estimates. Crop data can be transferred wirelessly from the machine, through VarioDoc Pro  and Agrirouter.

When it isn’t required for harvesting, the NIR sensor can be mounted on a slurry applicator  for constituent analysis instead.

Test drive

The farm in northern Italy proved an excellent location for the harvesting demonstration, with maize standing as high as the top of the Katana’s cab and yielding up to 108t/ha.  With the 8m, 12-row, Kemper 490 Plus header, and set to achieve a 5mm chop length, the Katana harvested 180–205t/hr, travelling at 3kph, at an engine speed of 1,850rpm. The spot-rate diesel consumption was impressively  low at 41 litres per hour, in the  damp heavy crop.

Cab noise levels are extremely low. The air conditioning maintained a cool cab even though it was approximately 40ºC outside.

Advantages of the Katana’s design include cruise control which allows the user to set a maximum engine working load which is maintained automatically by adjusting the travel speed, and the unblocking process which allows the feed rollers to be reversed without the table feed reversing at the same time – preventing the crop being ejected out onto the field.

Fendt forage harvester product specialist, Dan Woodward.

“The improved crop flow system transformed the smaller Katana when it was upgraded from the 65 to the 650, and the same system  will benefit owners of the new 850 too,” explained Dan. “We expect sales to be split equally between  the two models, with the new 850 likely to be selected by those with large areas of maize and wholecrop.

“Limited production of the Katana 850 starts in April next year, and we will be running demonstration machines of both sizes during the grass and maize harvesting seasons.

“Increased productivity  combined with significant fuel savings makes both models very attractive, and the cab is extremely comfortable too.”
