Abstract
A tool adapted to be removably joined to the bucket or dipper stick of a backbone or excavator is described. The tool is used to dig a footing at the base of a trench. The tool includes two major components: a frame and a tooth-shaped member. The frame carries a tooth-shaped member and the frame is removably joined to the bucket. The tooth-shaped member engages and uplifts the material at the base of the trench while the frame guides the tooth-shaped member and funnels the material uplifted from the base of the trench into the interior of the bucket. The tooth-shaped member can be formed together in one solid piece or from several flat plates that have been welded together. A bolting means can be used to join the tooth-shaped member and frame to the bucket.
