3. Wear of the tooth seat: When the tooth seat wears 10-15%, it is recommended to replace the tooth seat. There is a large gap between the worn tooth seat and the bucket teeth, so that the cooperation between the bucket teeth and the tooth seat And the stress point changes, causing the bucket teeth to break due to the change of the stress point.
