A small, four wheeled, stable utility vehicle (S4WSUV) for hauling and dumping material, articles or containers and especially adapted to operate in tight areas is disclosed. The S4WSUV has two widely spaced free turning swivel wheels and two widely spaced, independently driven rear wheels, a pivoting platform connected to a lifting mechanism for pivoting the platform to dump the material, etc. to a side of the S4WSUV. An engine drives a power source that can be a hydrostatic system, an electrical system or a mechanical system for motors driving the rear wheels. Optional features include a cantilever mounted seat assembly, foot and/or hand controls for steering, container mounts on the platform or a platform frame for securing one or more containers of various types and sizes and attachments for attaching one or more pieces of equipment for functions other than hauling and dumping.

The invention claimed is: 1. A small, four wheeled, stable, utility vehicle (S4WSUV) for tasks including hauling and dumping comprising; a) a frame having a length or lengths and a width or widths, b) four wheels, including widely spaced apart front wheels being supported by a front portion of the frame and mounted to freely swivel and two widely spaced apart independently driven rear wheels spaced from the two front wheels and supported by a rear portion of the frame with one of said independently driven rear wheels being on one side of the frame and the other independently driven rear wheel being on an opposite side of the frame, c) one or more engines, d) a motor or drive mechanism for driving each of the independently driven rear wheels in a clockwise and counter clockwise direction, e) a platform pivotly supported by a side of the frame for supporting material or one or more articles or one or more containers, f) a lifting mechanism communicating with a location off-center of the platform for pivoting the platform to dump the material, article(s) or the one or more containers on or attached to the platform to a location near a side of the S4WSUV and for retracting the platform to a hauling position, g) one or more power sources for powering each motor or drive mechanism and the lifting mechanism, and h) controls for activating each motor or drive mechanism and the lifting mechanism. 2. The S4WSUV of claim 1 wherein the one or more engines comprise an internal combustion engine. 3. The S4WSUV of claim 2 further comprising one or more electrical storage batteries and an electrical starter for the internal combustion engine. 4. The S4WSUV of claim 1 wherein the frame comprises one or more attachments for attaching a functional device for providing a function other than hauling and dumping material or articles. 5. The S4WSUV of claim 1 wherein the platform comprises one or more container mountings for securing one or more containers to the platform or a platform frame. 6. The S4WSUV of claim 2 wherein the platform comprises one or more container mountings for securing one or more containers to the platform or a platform frame. 7. The S4WSUV of claim 1 wherein the controls comprise foot controls for activating each motor or drive mechanism for moving and steering. 8. The S4WSUV of claim 2 wherein the controls comprise both hand and foot controls for activating each motor or drive mechanism for moving and steering. 9. The S4WSUV of claim 7 further comprising a cantilever mounted seat assembly at the rear of the S4WSUV for allowing an operator to stand or sit while operating the S4WSUV. 10. The S4WSUV of claim 8 further comprising a cantilever mounted seat assembly at the rear of the S4WSUV for allowing an operator to stand or sit while operating the S4WSUV. 11. The S4WSUV of claim 1 wherein the one or more power sources comprises a hydrostatic drive system for each motor or drive mechanism. 12. The S4WSUV of claim 2 wherein the one or more power sources comprises a hydrostatic drive system for each motor or drive mechanism. 13. The S4WSUV of claim 9 wherein the one or more power sources comprises a hydrostatic drive system for each motor or drive mechanism. 14. The S4WSUV of claim 10 wherein the one or more power sources comprises a hydrostatic drive system for each motor or drive mechanism. 15. The S4WSUV of claim 1 wherein the one or more power sources comprises an electrical generating device for supplying electricity to drive each motor or drive mechanism, each motor or drive mechanism being an electric motor. 16. The S4WSUV of claim 2 wherein the one or more power sources comprises an electrical generating device for supplying electricity to drive each motor or drive mechanism, each motor or drive mechanism being an electric motor. 17. The S4WSUV of claim 9 wherein the one or more power sources comprises an electrical generating device for supplying electricity to drive each motor or drive mechanism, each motor or drive mechanism being an electric motor. 18. The S4WSUV of claim 10 wherein the one or more power sources comprises an electrical generating device for supplying electricity to drive each motor or drive mechanism, each motor or drive mechanism being an electric motor. 19. The S4WSUV of claim 1 wherein the one or more power sources comprises a mechanical drive comprising a plurality of gears, pulleys, belts or chains for driving the rear wheels independently. 20. A small, four wheeled, stable, utility vehicle (S4WSUV) for tasks including hauling and dumping comprising; a) a frame having a length or lengths and a width or widths, b) four wheels, including widely spaced apart front wheels being supported by a front portion of the frame and mounted to freely swivel and two widely spaced apart independently driven rear wheels spaced from the two front wheels and supported by a rear portion of the frame with one of said independently driven rear wheel being on one side of the frame and the other independently driven rear wheel being on an opposite side of the frame, c) an internal combustion engine, d) a platform pivotly supported by a side of the frame for supporting material or one or more articles or one or more containers, e) a lifting mechanism comprising one or more hydraulic cylinders communicating with a location off-center of the platform for pivoting the platform to dump the material, article(s) or the one or more containers on or attached to the platform to a location near the a side of the S4WSUV and for retracting the platform to a hauling position, f) a hydrostatic drive comprising one or more hydraulic pumps and a hydraulic motor connected to each rear wheel for independently driving each rear wheel in a clockwise and counter clockwise direction, a hydraulic pump also providing power for a hydraulic cylinder, g) a cantilever mounted seat assembly at the rear of the S4WSUV for allowing the operator to stand or sit while operating the S4WSUV, and h) controls for activating each drive and the lifting mechanism comprising both hand levers and foot pedals for activating each drive.
