ABSTRACT:
A utility vehicle with foot-controlled mobility is provided that includes a skeletal frame structure supporting a gasoline engine which utilizes a belt drive system to drive hydraulic motors with one hydraulic motor disposed at each rear wheel. The vehicle includes four wheel and tire assemblies, substantially at each corner with the rear wheels being driven and the front wheels being formed as casters for 360° rotation to provide a zero turning radius vehicle. The user sits upright in a manner wherein the user's legs are supported on pivotal leg support plates to allow the user to sit upright with legs directed down and away from the waist to allow the user to operate a hand-held implement. Both speed control and directional control are provided using pivotally mounted pedals with one pedal controlling each hydraulic motor. Movement of the pedals allows individual motor control to provide drive steering and speed control.
