Fendt introduces Katana 850 forage harvester

Share this item

With the Katana 850, Fendt is entering the 800hp+ forage harvester market. Innovations such as the revised crop flow, the reversible fan with variable fan blade pitch technology fan and a new 12-row header meet the requirements for high efficiency and output.

Ten years after the delivery of the first Fendt Katana forage harvesters, Fendt is expanding its forage harvester model range with a new generation of high hp machines.

The Fendt Katana 850 is equipped with an in-line 6-cylinder engine from Liebherr. With a displacement of 18 liters, it has an output of 847 hp/623 kW (ECE R120). The engine complies with the European Stage V emissions standard with selective catalytic reduction (SCR) without a diesel particulate filter or exhaust gas recirculation. This protects the engine, reduces the required cooling power and fuel consumption while meeting all standards.

The in-line 6-cylinder engine is precisely matched to the requirements of a forage harvester in terms of its torque characteristics and features by particularly low maintenance costs, helping to keep cost of operation in check. If the full power of the forage harvest isn’t required, it can be operated in fuel-saving Eco Mode. In Eco Mode, the usual running speed of the chopping cylinder is maintained at reduced engine speed. The design of the engine fitted to the Fendt Katana makes it possible to work fuel-efficiently, in both full-load and partial-load operation.

As an option, the Fendt Katana 850, like the Katana 650, has a reversible fan with variable fan blade pitch technology fan. The pitch of the individual fan blades can be adjusted as required. This means that the exact cooling capacity is always achieved. If the full cooling capacity is not required, the power saved at the fan is fed into the rest of the machine. The reversing function on the fan cleans the cooling package of debris and fine dust. The automatic control of this function relieves stress on the driver and means they can focus on the job at hand.

Optimal performance in large crops

Optimised crop flow has a significant impact on the machine’s throughput and chop quality. When developing the crop flow, the focus was on a uniform feed flow at high throughputs and, at the same time, minimal power requirements. In addition, the Kemper 490plus a header with a12 row working width is available for the Fendt Katana. With this header, the full power of the machine is fully utilised and harvesting time windows are optimised. Further advantages are gained through the improved ground following capability of the header due to a third skid and shortened set-up times. The header is suspended on the pendulum frame of the Fendt Katana 850 and allows for variations of up to 14°.

The six pre-compression rollers on the feed intake ensure optimum pre-compression of the forage. This provides good chop quality and chop length consistency. Metal and stone detectors on the first pre-compression rollers prevent damage to the chopping cylinder. In the rear area of the feed intake, the crop volume is recorded via a sensor. This data is then available for yield monitoring and documentation.

With a diameter of 720 mm, the Fendt Katana 850 has the largest chopping cylinder on the market. The large diameter of the cylinder with its high flywheel mass ensures smooth running and increases driver comfort. Optional chopping cylinders with 20, 28 or 40 knives are available for the forage harvester. These cover chop lengths of between 2.6 and 41.4 mm.

The position of the knives allows a pulling cut and thus an excellent chop quality. The knives are fixed by means of a slotted hole. This allows the knives to be repositioned once and thus the entire length of the knife can be utilised. This significantly extends the life span of the individual knives.

Less wear and increased longevity

Specially developed for gentle grinding, the Fendt Katana’s knife sharpening system continuously adjusts the sharpening stone during sharpening. On the one hand, the knives sharpened very evenly, on the other hand, the service life of the knives and the shear bar is significantly increased. This reduces maintenance costs.

Fendt offers three different roller crackers with a diameter of 300 mm. The standard R cracker with sawtooth profile is suitable for chop lengths of up to 20 mm. The optional RS cracker with V spiral groove has been developed for optimal processing with longer chop lengths, up to mm. The speed difference of 30 or optionally 40 percent ensures thorough processing of the crop. This ensures that all the nutrients can be extracted from the crop when it is used.

Up to 6.20 meters loading height

The revised discharge chute can be precisely controlled and centred. The crop is accurately blown into the trailer and losses during chopping are avoided. The loading height of up to 6.20 m ensures targeted transfer of the crop, even with large trailers. The Fendt Fill Control filling assistant is available as an option for the Fendt Katana 850. If the discharge chute swivels, the discharge flap is automatically controlled and trailers are filled more evenly. This takes pressure off the driver, giving them time to focus on feeding crop into the machine and increases operating comfort. In addition, the position of the camera directly next to the discharge flap allows the best view of the crop flow.

To support the fermentation process, drivers can optionally carry a silage additive system. The ex works system is fully integrated into the vehicle and has a tank capacity of 215 l.

Also optionally, Fendt offers an interface for an NIR sensor. This allows farmers and contractors to measure the dry matter content of the crop, among other things. An ISOBUS interface enables the use of different sensors. In addition, the recorded data facilitates accurate billing for both farm and contracting operations.

As with the Fendt Katana 650, the intelligent all-wheel drive system Fendt Balanced Grip is also available as an option for the Katana 850.

The Fendt Katana 850 forage harvester is available for the 2023 season.
