Lifting and crushing apparatus for tree stumps
摘要:
A stump lifting and crushing device for mounting to an end of a bucket arm of a digging machine includes stump lifting hooks and a bit pivotally closable with a counter bit for crushing stumps therebetween. The bit has an elongated narrow cutting surface which cooperates with an aligned counter surface provided by the counter bit. The counter surface extends transversely across the width of the cutting surface of the bit. The closing movement of the bits is limited by the cam-like engagement of a following member of the bit with a stop member of the counter bit.
