An agricultural tillage implement has a steerable rear axle which facilitates the implement more faithfully following a towing unit. The implement has a solid axle mounted to the main pull frame that allows for vertical movement of the implement to switch between field operation and a transport configuration. Attached to the solid axle are two steering knuckles that are tied together by an adjustable tie rod and two hydraulic steering cylinders. On each knuckle is a set of walking tandems to which the tires are mounted. The two cylinders are connected to an auxiliary port in a towing traction unit to enable the steering function without having to turn the unit steering wheel. The arrangement allows the steering knuckles to turn up to 25 degrees in either direction.
