<p>An improved hydrostatic transmission control system includes a main control valve which varies the speed at which a vehicle is driven as a function of variations in throttle setting, engine output speed, and displacement of the hydrostatic transmission. Upon actuation of a brake pedal, a linkage effects a deswashing of a pump unit in the hydrostatic transmission to reduce the speed at which the vehicle is driven. Continued actuation of the brake pedal causes the linkage to effect engagement of the vehicle brakes.</p> |
