ABSTRACT:
A subsoil plowing implement having winged subsoil plows that break and lift the soil thereby loosening said soil. The plows are mounted so that an upper surface of the wing of the plow may be oriented at varying degrees of incline to horizontal. Spikes are located at a leading edge of the wing and a shank so that said spikes precede the wing and shank through the soil. The spikes initially break the ground and reduce the resistance that the wing and shank experience as they progress through the soil. A bevelled and sharpened deflection strip fixed to a leading edge of the shank making said shank more knifelike and allowing it to cut through the soil with reduced friction. By varying the arrangement and orientation of the plows, areas of loosened soil with different cross-sectional shapes are created.
