An agricultural planter which provides an improved method for extending and retracting the wing boom and which has improved maneuverability is disclosed. A drive member is provided that drives one or more of the wing wheels on the agricultural planter. The drive member may be, for example, a hydraulic motor or an electric motor. When a wing boom is extended or retracted between the transport position and the working position, a controller generates a command signal to the drive member to drive one or more of the wing wheels forward or reverse, thereby assisting the wing boom in retracting or extending the telescoping portion of the hitch assembly and in extending or retracting the booms. During operation, the controller may similarly generate a command to the drive member to drive one or more of the wing wheels either in forward or reverse according to the operation of the towing vehicle.
