ABSTRACT:
A tree shear comprises a base with a tree receiving position. There is an undercutting blade mounted on the base for making a groove extending partway through a tree from one side of the tree and thereby inducing a bending of the tree trunk and putting under tension fibres in the tree trunk near the opposite side. There is a shear mounted on the base for then shearing the tree from the opposite side.
