  • Patent number: 5348361
    Abstract: This invention relates to a tree mover for relocating small trees. The tree mover is designed to dig a hole to receive a tree having a root ball, dig up a tree and deposit a tree in a hole. The tree mover comprises loader buckets having concave inner surfaces pivoted between an open position for digging and a closed position for lifting. Pusher blades are mounted so as to be closely spaced from said inner surfaces and to be movable between a raised position and a lowered position. These pusher blades enable the integrity of a root ball of a tree to be retained. They also may be used to clean dirt from the surface of the bucket.
