    Abstract: An implement to remove levees and the like from the earth's surface includes a frame means with longitudinal and lateral members connected to form a frame having sides, a front and a rear end. A pair of ganged disc harrows is supported on the frame and depends therefrom. Each of said pair of said ganged disc harrows extends inwardly from a side of the frame and towards the rear end of the frame to form a generally V-shape with the apex of the V-shape being disposed adjacent the center longitudinal axis of the frame. Dozer blade means comprised of a pair of dozer blades. Each of the dozer blades extend from a side of the frame and inwardly towards the front end of the frame to form a generally V-shape with the apex of the V formed by the dozer blades being disposed adjacent but rearwardly of the apex of the V formed by the ganged disc harrows.
