A new cylinder type forage cutter with high operation was designed and manufactured. Construction design and its performance parameters, helical angle of moving knife, setting height of fixed knife, overload protective device, throwing device and edge shape of fixed knife were analyzed. The results of test were as follows: optimal helical angle of moving knife was 20°, optimal setting height of the center of the cylinder above fixed knife was 20 mm, line speed of blower vane was 13.6m/s ,power consump...
