The linkage is activated by a foot pedal leverwhich stows behind the driver's legs and a mechanism for locking the foot pedal lever inposition behind the driver's legs and releasing it only when the driver depresses the footpedal lever. The side wheels are further automatically steerable in synchronism with thevehicle front wheel by a mechanism which detects the front wheel position and activatesan electrical motor to position the side wheels in accordance with the front wheelposition. The steering mechanism is further capable of steering the side wheels to aposition perpendicular to the track of the vehicle.
