Abstract

Speed control apparatus for controlling a hydrostatic transmission in a range of speed conditions including a zero speed position, consisting of a hydrostatic drive device and an output shaft operable in that range, characterized by a hydraulic brake circuit that it can be selectively actuated when said transmission is placed in the zero speed position to apply the braking pressure to said shaft.
