  • Patent number: 7240488
    Abstract: A control arm is coupled to a control shaft of a hydraulic pump. A friction shaft extends parallel to the control shaft and is slidably moveable within an arcuate-shaped hole in the control arm. A stop plate is movably supported by the control shaft and the friction shaft. When the stop plate is in the operating position, a friction pad supported by the friction shaft is biased by a pressure plate and a spring against the control arm. When the stop plate is in the braking position, a sloping region of the stop plate engages a pin extending from the pressure plate such that the friction pad is spaced from the control arm and arcuate-shaped grooves in the stop plate engage pins extending from the control arm in a neutral position. The present invention also includes a hydrostatic transmission and a vehicle incorporating the cruise control and neutral return mechanism.
