Abstract

A control device for a hydrostatic transmission including apparatus for sensing a speed of a prime mover which powers a variable displacement pump of the hydrostatic transmission and for regulating the displacement of the variable displacement pump in accordance with the speed of the prime mover, is disclosed. The control device also includes apparatus for transmitting a mechanical feedback signal representative of the displacement of the variable displacement pump to the control device to maintain the variable displacement pump at a displacement proportional to the speed of the prime mover.
