Abstract
A drill attachment for removing weeds and the like from the ground, which has a body with a shaft protruding from the center and at least two prongs protruding from the opposite side of the body. The free end of the shaft is placed into the chuck of an electric drill, and the prongs are forced into the ground around a weed. The user operates the drill, thus spinning the prongs around the weed. The prongs entangle the weed's roots and bore a small hole in the ground, allowing the user to easily remove the weed. The prongs are then placed into the ground close to the hole, and the drill is slowly operated, thus refilling the hole. The device has a plurality of edges and corners that allow the operator to shear weeds and the like that become entangled on it.
