Abstract
A steerable agricultural implement configured to be coupled to a tractor by a multi-point hitch system that restrains side-to-side articulation between the tractor and the implement. The agricultural implement includes a steering controller that receives a positional attribute from a steering system of the tractor and controls a degree of pivot of a wheel assembly of the agricultural implement based on the positional attribute of the tractor steering system. The wheel assembly is configured with a steering actuator that is operable to pivot a portion of the wheel assembly without transmitting force beyond the wheel assembly, abutment stops to define maximum degrees of pivot of the portion of the wheel assembly and relieve the steering actuator without transmitting force beyond the wheel assembly, and a quick release free-wheel mechanism to enable a disconnected or 'free wheel' operation of the wheel assembly independent of the steering actuator.
