ABSTRACT:
A tree-removing device designed for mounting on a land vehicle such as a conventional bulldozer or tractor and having a bulldozer-type blade fitted with a power blade for cutting the roots of a tree and a tree jack for levering the tree from the ground after the roots are cut. The power blade is characterized by a frame pivoted to the bulldozer-type blade and a vertically-adjustable blade carrier mounted in the frame and internally fitted with a hydraulically-operated blade which may be extended into the ground from the blade carrier to cut the roots of a tree by operation of the land vehicle. The tree jack includes a jack frame pivoted to the land vehicle bulldozer-type blade and a mast extensibly attached to the jack frame, which jack frame is fitted at one end with a foot for engaging the tree. The mast includes hydraulic cylinders for both engaging the tree and causing the mast to pivot, thereby jacking the tree from the earth by operation of the jack frame foot.
