Title: TREE EXCAVATOR
Abstract: An excavator for excavating a tree and forming a root ball consisting of an excavator scoop (18) having a plurality of segments (24, 26, 28, 30) mounted for movement with respect to one another between a nested position in which the segments are nested one within another and a deployed position in which the segments are extended from one another and cooperate with one another to form a bowl-shaped scoop. A drive mechanism (22) is provided which serves to drive the segments from the nested position to the deployed position, such that when the nested segments are located adjacent a tree and then driven to the deployed position the segments will pass under the tree to excavate the tree and from a root ball within the deployed scoop. The excavator is mounted on a crane (14) which is in turn mounted on a truck (12). The crane serves to manipulate the excavator between a ground contacting position and a load transporting position. In this load transporting position a tree is supported with its root ball in the scoop and its trunk (170) and branches (174) extending toward the back end of the truck.
