ABSTRACT:
A tree shear apparatus includes first and second blades, and linkage means interconnecting the blades so that the first blade makes a partial, relatively small cut of the tree and withdrawal from the tree while the second blade cuts through the tree so that the first and second blades together make a complete cut of the body of the tree.
