Abstract :In this study, active knife and fixed knife of single-row disc silage machine has three different clearance C1, C2 and C3 insert ignore into journalissuearticles values(1, 3 and 5 mm); and it is tried in three different working speed V1, V2 and V3 insert ignore into journalissuearticles values(1.8, 2.5 and 3.7 km / h); and PTO speed insert ignore into journalissuearticles values(540 min-1); and machine\`s fuel consumption insert ignore into journalissuearticles values(l/h);, average power consumption insert ignore into journalissuearticles values(kW);, field energy consumption insert ignore into journalissuearticles values(kW/da);, product energy consumption insert ignore into journalissuearticles values(kW/t);, field working capacity insert ignore into journalissuearticles values(da/h);, product working capacity insert ignore into journalissuearticles values(t/h); and Chopping size distribution characteristics of the fragmented material were determined. It has been found that knife-counter knife clearances smaller than 3 mm insert ignore into journalissuearticles values(1 mm); and larger insert ignore into journalissuearticles values(5 mm); have a negative effect on machine performance in general. In terms of fuel and power consumptions, the most suitable combination of work was C2V1, and in terms of field-product energy consumption, C2V3 combination was found to be optimal. The highest field-product working capacity was achieved at the V3 working speed. In terms of silage mincer size, all working combinations gave the appropriate shredding length distribution; especially the 1st knife-counter knife clearance insert ignore into journalissuearticles values(1 mm); was determined to give a more suitable Chopping size distribution in terms of animal feeding. In the second clearance insert ignore into journalissuearticles values(3mm);, both the energy consumption and the Chopping size distribution were positive.
