ABSTRACT:
The present invention relates to a support for an earth working tool such as a chisel plow, and more particularly to a spring loaded support which permits pivoting of the earth working tool against a resilient bias force for prevention of overstress, and which includes a mounting member that distributes the stresses on the earth working tool shank itself across a substantial length of the shank to reduce stress concentration areas and lower the maximum stresses by providing a spring backing member along the shank which carries the mounting pivot tube and also carries one end of the spring assembly.
