  • Method of transplanting large trees
    Patent number: 5265375
    Abstract: A method of moving large trees is disclosed. The method includes digging a trench around the tree at a depth and distance from the trunk of the tree to provide a ball large enough to sustain the tree after it is severed from the ground until the tree can be replanted, placing the side walls of a container in the trench to support the sides of the ball, moving a cutter horizontally under the ball from one side to the other, pushing support members under the ball behind the cutter as the cutter moves under the ball so that when the cutter moves out from under the ball, the ball will be completely supported by support members.
