Abstract
An agricultural implement includes an elongated carrier frame with support wheels. One or more tool sections, each having tools mounted to a tool mounting bar, are mounted to the carrier frame. The tool sections are independently raised and lowered between the transport and use positions by hydraulic cylinders. The carrier frame is attached to a tractor by a hitch assembly which includes a control link. With the tractor in the use position, the control link steers the support wheels in the forward direction. In converting the implement for transport, an hydraulic cylinder actuated by the operator from the tractor, uncouples a portion of the hitch assembly and permits the control link to rotate as the tractor is driven to the side of the carrier frame. In thus rotating, the control link actuates the steering mechanism to turn the support wheels so that they all face the side and are aligned with the tractor which transports the implement from the side, parallel to the direction of elongation of the carrier frame. As the tractor turns during transport, the control link and steering mechanism steers to support wheels.
