Abstract
A hitch flexing hinge included within the draft beams of an implement frame of the type that enables vertical flexing of the frame sections. The hinge includes a yoke attached to the drawbar of a draft vehicle and a body section that is received in one end of the draft beam. The body portion carries a swivel ball and attachment of the draft beam to the swivel ball allows rotational twisting of the draft beam about its longitudinal axis as the implement frame sections flex.
