Working principle of grass cutter
1. Turn on the rotor motor.
2. Turn on 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 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.
type three 10t/h 16t/h chaff cutter
Advantage of grass cutter
- Cutting grass machine adopts chain automatic feeding device that is suitable for forage with long diameter, saving labor time
- Double-pushing roller suction and cutting device to enable the good cutting effect without any blockage, improving working
- Cutting grass machine is equipped with a detachable walking wheel for easy movement.

FAQ of grass cutter
- What should I do if there is blocking?
The reverse switch can be pulled to “stop”, then pulled to the “reverse”.It is strictly forbidden to remove the blocked straw by hand without stopping the machine.
- How to increase the gap of the roller?
First, loosen the center screw on the upper platen of the machine, 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 roller is flexible.
Finally, tighten the bolt on the center screw.
Adverse action will decrease the gap.
