An agricultural vehicle has an implement connection hitch which is moveable relative to a rear axle of the vehicle. A system for controlling movement of the connection hitch is coupled with position sensors such as a GPS receiver. During turning maneuvers, the control system moves the hitch relative to the rear axle of the vehicle until it reaches an offset position such as to reduce the turning circle of the vehicle and a connected implement. The extent of offset may be determined automatically by the control system on identification of a connected implement.
