  • Publication number: 20050115760
    Abstract: A speed control system for a utility vehicle, the vehicle having a forward-facing driving position and a rearward-facing seat, includes a creep control system for moving the utility vehicle, controlled from the rearward-facing seat. The vehicle includes a speed-controllable transmission operable to output power to drive a wheel. The vehicle includes a creep speed control actuator located adjacent to the rearward-facing seat and a creep speed control system operatively connected to the actuator and to the transmission. The system converts movement of the actuator to speed change of the transmission. The transmission can be a mechanically or electronically controlled hydrostatic transmission, or an electronically controlled reverser transmission.
