Abstract
An implement hitch for an articulated agricultural four-wheel drive tractor includes draft links secured to the rear section of the tractor by spherical bearings and carrying couplers to connect an implement. Loads applied by the implement act along lines through spherical bearings in the ends of each draft link and extend into the tractor to converge and intersect slightly in front of the rear axle of the rear section of the articulated tractor.
