Disclosed herein is a control for a hydrostatic transmission, which control includes a control member operatively connected to the transmission for selectively moving the transmission between forward, neutral and reverse positions in response to control member movement, a pivotally movable member, an actuating member mounted for movement between forward, neutral and reverse positions, means connecting the actuating member with the movable member for pivoting the movable member in response to actuating member movement and connecting the actuating member and the control member for moving the transmission between forward, neutral and reverse positions in response to actuating member movement, and first and second arms pivotally mounted coaxially with, and independently of, the movable member and having outer free ends located in spaced relationship to each other. The movable member is engageable with the second arm so as to displace the second arm in a first pivotal direction in response to actuating member movement from the neutral to the forward positions and so as to displace the first arm in the opposite pivotal direction in response to actuating member movement from the neutral to the reverse positions, a spring biasing the arms toward each other, and a stop disposed between the arms for engaging the first arm so as to prevent pivotal movement thereof in the first direction when the second arm is pivoted by the movable member in the first direction and for engaging the second arm so as to prevent pivotal movement thereof in the opposite direction when the first arm is pivoted by the movable member in the second direction. |
