Abstract
A novel lifting tool suitable for lifting rooted trees and the like from the ground at least includes the following: a least one main boom; at least one outrigger coupled to a first end of the main boom; at least one mounting member coupled to a second end of the main boom, the mounting member adapted to couple the main boom to a lifting force machine; and at least one set of tongs coupled to the main boom, the tongs adapted to clamp a tree or the like to be lifted around at least a portion of the periphery of the tree or the like, and lift the tree or the like when the main boom is lifted. The tongs are located along the main boom at a position to multiply the force input by the lifting force machine. In the preferred embodiment, the lifting force machine is subsumed by a skid loader
