Abstract
A plow shank has a digging blade attached to the lower extremity thereof by an adaptor. The digging blade has an inclined upper arcuate surface to which the adaptor is releasably secured. The adaptor is also releasably secured to the lower extremity of the shank, such that the blade is located below the lower extremity of the shank to enable the blade to present a low forward facing rounded profile.
