Abstract
A draft link of an agricultural tractor three-point hitch has a recessed pocket on the inside surface thereof. The recessed pocket has a convex back wall surface with a center of curvature. A bumper is disposed in the pocket and has a concave inner surface complementary to the convex back wall surface of the pocket. The convex outer surface of the bumper is eccentric to the convex back wall surface of the pocket resulting in a wedge shaped bumper. The bumper is rotatable in the pocket about the center of curvature. The position of the bumper in the pocket determines the extent to which the eccentric outer surface projects from the pocket. This projection determines the amount of lateral sway of the draft link.
