The Fendt Katana 650 comes with 2 all-new roll conditioners with a large roller diameter and a huge processing surface. No grain gets past the ultra efficient R-Cracker with a sawtooth profile. Especially for long-cut silage, the RS-Cracker with its sawtooth profile and additional counter-rotating V-spiral groove is the perfect choice. Even woody parts of the stalk are completely spliced thanks to the overlapping longitudinal and transverse pulping motion of the additional spiral groove.
