This invention relates to an improved soil contact tool comprised of a narrow uniform width ground engaging section and a triangular moldboard section extending therefrom. The moldboard section has a center to direct soil away from the mold board with sides being generally concave to insure transverse movement of the soil to create ridges on either side of the ground working tool.
