Abstract
A wedge shaped bumper for the draft link of a tractor three point hitch is adjustable along the length of the draft link and has a concave curved surface in the longitudinal plane of the draft link. The longitudinal curve allows the bumper to be shorter in length than a flat surfaced wedge bumper while providing the same change in thickness. The bumper mounts to the draft link in a longitudinal channel formed by upper and lower walls on the draft link having tapered engagement surfaces to transmit vertically loading from the bumper to the draft link without shear loading of the bumper mounting bolt.
