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.

The reverse switch can be pulled to “stop”, and then pulled to the “reverse”.It is strictly forbidden to remove the blocked straw by hand without stopping the grass cutting machine.

How to increase the gap of the roller?

First, loosen the center screw on the upper plate of the grass cutting machine, and adjust the sliding plate and sliding block clockwise.
Second, adjust the bolt on both sides counterclockwise to the appropriate position. The gap between the two rollers should be Horizontally the same, and the upper and down rollers should be flexible.
