ABSTRACT:
A detachable, self-sharpening digging shoe for deep tillage shanks is shaped, sized and disposed in a manner to provide the proper angle of attack and to minimize resistance to its movement through the soil such that the movement is not only smooth but incapable of creating that kind of soil turbulence which normally results in substantial wear on critical areas of the shoe and the shank.
