Fendt Katana 850 forage harvester: An endurance test • Last season’s woeful conditions for maize harvest certainly proved a challenge for our test Fendt forager … as, to be fair, they would have done for any harvester. Apart from a few minor details, the 850hp Katana 850 put in a decent performance.
