ABSTRACT:
An implement has a frame including beams assembled end to end in the shape of a W with deep tillage members depending from each beam. A towing hitch is connected to the middle of the assembly so that during operation, the beams are inclined with respect to the towing direction and the tillage members can plow deep. An elongated crumbler roller supports the rear of the frame and front ground wheels adjacent the frame sides support the front of the implement.
