Abstract
A one-piece shank assembly is disclosed which is comprised of a flat leaf spring having an arcuate intermediate portion, a lower end portion adapted to mount a ground working tool, and an upper end portion which is reversed upon itself to thereby form a pivot sleeve at the forward end of the shank. The leaf spring is brought rearwardly in contiguous and overlying relation to the intermediate portion and its terminal portion is then again reversed upon itself upwardly, forwardly, and then downwardly to form a sleeve bearing for the lower end of a pressure rod. Also disclosed is a simplified mounting assembly for the shank comprised of a pair of rearwardly facing and pivotally connected U-shaped channel members, portions of which are cut away to receive and clamp the frame bar of a ground-working machine in an effective and efficient manner.
