A pair of main wheels carry the pivot means and front and rear castor wheels carry the front and rear extremities of the respective front and rear frame portions. Control means is provided for driving the main wheels independently for steering the vehicle whereby such vehicle may be maneuvered in relatively restricted areas and articulation of such frame will enable the castor wheels to shift vertically with respect to the main wheels to accomodate uneven and irregular terrain.
