ABSTRACT:
A hydraulic drive apparatus having an actuator assembly mounted on a control device is disclosed. The hydraulic drive apparatus comprises an input, a hydraulic pump, a control device, and an actuator assembly. The hydraulic drive apparatus is mounted on a vehicle that comprises an operating system. A prime mover drives the input, which subsequently drives one or more axle shafts. The transmission is capable of operation in forward and reverse directions. The control device determines the direction of operation and speed of the transmission. The actuator assembly is mounted to a component of the control device. The actuator assembly determines the state of operation of the output device with respect to the forward or reverse operation of the transmission.
