Patent abstract
A hole cutter includes a frame and first and second blade halves moveably mounted with respect to the frame. The blade halves are first driven into the ground and then are lifted upwardly out of the new hole with as ground plug therebetween. A lift flange engages both the blade halves during this upward movement. Then the blades and the ground plug are inserted into an old hole and the blades are removed simultaneously to leave the ground plug in the old hole. The frame is longitudinally extensible to create this removal of blade halves from the old hole.
