The motor (diesel engine or wheeled tractor) is used as the supporting power. Power is transmitted to the main shaft, and the active V-belt at the other end of the main shaft transmits the speed-regulated power to the grass roller through the triangle belt, clutch wheel, gear box, universal joint, chain, etc. When the material to be processed enters the upper and lower pressure Between the grass rollers, it is clamped by the grass pressing rollers and fed into the guillotine cutting mechanism at a certain speed. After being cut by a high-speed rotating cutter plate, it is thrown out of the machine through the discharge port.
