Working principle of grass cutter

1. Turn on the rotor motor.

2. Turn on the automatic geared motor to drive the automatic feeding device after the operation is stable.

3. The operator evenly spreads the straw on the automatic feeding plate and the inlet gradually, and raw material goes into the drum from the cutting device at a high speed.

4. Blades hit tear, and smash them into a filament shape at this time.

5. Finally, grass is thrown out of the machine by centrifugal force.
