ABSTRACT:
An excavator for excavating a tree and forming a root ball consisting of an excavator scoop having a plurality of segments 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 fron one another and cooperate with one another to form a bowl-shaped scoop. A drive mechanism 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 evacavate the tree and form a root ball within the deployed scoop. The excavator is mounted on a crane which is in turn mounted on a truck. 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 and branches extending toward the back end of the truck.
