How To Choose A Best Chaff Cutter

Several common faults and solutions during using the chaff cutter machine:

1. The machine has large vibration or strong noise.

The cause of the failure: the weight difference between the corresponding two sets of hammers is too large; individual hammers are not thrown off by the circlip; the bearing is damaged; the main shaft is bent and deformed; the weight of other parts on the rotor is different, causing the rotor to be unbalanced.

Solution: Match the hammers so that the weight difference does not exceed 59; the hammers can rotate flexibly; replace the bearings; correct or replace the main shaft; balance the rotor.

2. The straw machine is stuck and the sound is abnormal.

The cause of the failure: the screw of the fastening machine is loose; the blade gap is too small; metal, stones and other hard objects enter the inside of the machine.

Solution: Check the cutter head to see if the fixed blade screw is loose; adjust the blade gap to the standard requirements; stop the machine for inspection, and open the machine to remove foreign objects.

3. Overheating of the grass cutter bearing.

Cause of failure: too much lubricating oil, too little or poor oil quality; bearing damage;

Solution: Add lubricating oil as required; replace the bearing; straighten the main shaft; balance the rotor; replace the oil seal; reduce the amount of feed; adjust appropriately.
