UTILITY HAULING VEHICLE HAVING FOUR WHEEL DRIVE Abstract of the Disclosure A utility hauling vehicle includes at least one steerable wheel suspended from the forward end of a rigid frame of the vehicle and front and rear pairs of unsuspended drive wheels mounted to the rigid frame rearwardly of the steerable wheel. The front pair of drive wheels is differentially driven and the rear pair of drive wheels is respectively coupled for being driven in unison with the front pair of drive wheels. A differential lock is provided for locking the rear pair of drive wheels and, hence, the front pair of drive wheels for rotation in unison. The suspension for the steerable front wheel or wheels acts to lift the forward end of the frame to transfer weight to the rear pair of drive wheels. Weight transfer can also be accomplished by mounting the front pair of drive wheels at a level above the rear pair of drive wheels. The vehicle has a load bearing zone substantially within a vertical projection of the largest area occupied by the drive wheels.
