ABSTRACT:
A tree pusher for safely felling a tree. The tree pusher includes (a) a base; (b) a frame mounted on the base; (c) a mechanism for pushing the frame against the tree to fell the tree; and (d) a mechanism for connecting the base of the tree pusher to the tree, so that the base will not move while the tree is being pushed over to fell the tree. The frame includes a detachable pronged head which engages the trunk of the tree, and which disengages itself from the frame of the tree pusher and remains with the trunk of the tree as the tree falls. The frame includes a series of tubes connected end-to-end by locking pins, making it very easy to assemble and disassemble the tree pusher. If a tree has accidentally fallen against a house, a building, or an electrical power line, two tree pushers are positioned on opposite sides of the fallen tree and used to lift the fallen tree.
