This product is powered by the main motor and feeding motor. The feeding motor transmits the speed-adjusted power to the grass pressing roller through the universal joint, gear box, transmission shaft, etc. When the material to be processed enters between the upper and lower grass pressing rollers through the conveyor chain, it is clamped by the grass pressing roller and fed into the cutting (kneading) mechanism at a certain speed. At the same time, the main motor transmits power to the main shaft through the triangle belt. The main shaft drives the cutter holder to revolve at high speed to shred (knead) the material and throw it out of the machine via the discharge port.
