Argo ATV Control Modifications were made to Slippery Rock, PA, farmer Jack Losco's eight-wheel Argo ATV, which already had hand-operated skid steering. He replaced the vehicle's bench seat with a bucket seat from a Chevy Astro minivan, and mounted foam-wrapped steel tubing on both sides for greater stability. The original seat mounting brackets were lowered to accommodate the larger bucket seat, as was the fuel tank beneath it. Losco replaced the original hand-operated, twist-type throttle (like that found on a motorcycle) with a ¼-inch steel rod that runs from the steering levers through a hole in the instrument panel to the carburetor where it's connected with a reversed linkage, making it a push throttle instead of a pull throttle. He also hinged two vertical rods to the seat mounting brackets (one on each side of the seat) and ran adjustable, horizontal bars from the rods to the steering sticks, so he could steer without having to extend his arms (see figure). Plastic hand splints that slide on and off the top of the vertical rods eliminate the need to grip them to steer. The ignition and light switches and the choke control were all extended for easier access. The gearshift lever was also extended so the plastic hand splints on the steering rods would slip over it, allowing for non-grip shifting. A roll-over protection structure was added for safety.
