Field Test | Fendt Katana 850 forage harvester: Bella Katana

In Italy, the Fendt Katana 850 was put to the test. The Fendt forage harvester demonstrated strong throughputs and impeccable cutting quality.

Good To Know Points:

-         The Fendt Katana has a perfect chopping structure.

-         850 Liebherr horsepower are efficiently converted into throughput.

-         With these values, The Katana has nothing to hide.

Although the Katana had a lot of mass in front of it at 61 t/ha, the maize of the Dekalb DKC 6812 variety had relatively small, rubbery kernels despite irrigation. The grains of the dent corn variety were difficult to crack. The roller cracker with a 40 % difference in speed had to remain relatively close together during the throughput and chop length measurements (1.75 mm). The only difference to the Katana 850 from last year was the difference in speed of the cracker.

The cutting length had been varied from 4 to 13 mm. Due to the large, even surface, it was possible to repeat each measuring run three times. With 32 to 36 % dry matter, the maize yielded a very good 21 t/ha DM.

The Fendt Katana 850 forage harvester delivered high throughputs

At 4 mm and achieved close to 260 t/h of FM throughput. At 7 mm, the throughput increased by 20 t to 289 t/h. Each 3mm increase in chop length brought another 15 t/h more fresh mass onto the wagon!

The Katana chopped a maximum of 320 t/h, which is 110 t/h of dry matter or 5.25 ha/h.

In relation to the maximum output of 847 hp specified by Fendt for the Liebherr power unit, the Katana 850 achieves 0.1 to 0.13 t/h DM per hp. These are top values with which the Katana can and may compete with other makes in this performance class.

Diesel consumption was also very good. 0.44 l of diesel per ton of fresh mass is one of the lowest values we have found in this chopper class.

Perfect chop quality

At a chop length of 4mm, a good 60 % of the material is in the fraction up to 6 mm and over 90 % in the fraction up to 10 mm - chop qualities that we have never measured before!

Overlengths were virtually non-existent in all our samples.

Regardless of the chop length, the CSPS values were between 51 and 62% and therefore only in the average range.

Fendt Katana 850 in maize: Performance in practice

With increasing chop length, the fresh mass throughput increased by 23.3 % and the dry mass throughput by 28.2 %.
