Abstract
A compact, leaf spring biased shank assembly with a shank bracket which clamps to a tube and leaves the upper portion of the tube relatively unobstructed to eliminate interference with the lift mechanism and/or implement frame. The shank bracket includes easily accessible down pressure and shank height pins for quick, effortless adjustments of the shank assembly. The leaf spring is C-shaped and is designed to approach a straightened condition as the shank moves.
