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.

A tractor hitch comprising a pair of draft links mounted on opposite lateral sides of a tractor frame and extending rearwardly therefrom, a bumper on each of the draft links and a sway block on each lateral side of the tractor frame for engagement by the bumpers to limit sway of the draft links, each sway block having a laterally outward contact surface for engagement with the associated bumper, the sway block contact surface having a curvature of a first radius in a plane parallel to a longitudinal axis of the draft link and the bumpers being tapered lengthwise of the draft link and being adjustable in position lengthwise of the draft link, the bumpers having a contact surface with a curvature of a second radius in a plane parallel to a longitudinal axis of the draft link.
