Abstract
A conservation tillage unit for use in primary tillage includes a rolling coulter followed by a chisel plow having a narrow shank and a soil working unit mounted to the bottom of the shank. The working unit includes a point and a delta wing mounted behind and above the point, and forward of the shank. The working unit fractures the soil beneath the surface without throwing the surface soil and residue to the side and while leaving only a narrow furrow behind the shank even at ground speeds up to five to seven miles per hour.
