    摘要： it is shown a control linkage for a differential lock and a brake comprising a manual control having a first stage and a second stage of movement; a lost motion coupling (43) connecting the manual control to a brake and a differential lock, the first stage of manual control movement locking the differential before the second stage of manual control movement progressively engages the brake.

    摘要： An electrohydraulic actuator for a hydrostatic transmission includes a pair of pressure control valves (112,114) between a hydraulic pressure inlet line and a pair of passages to a cylinder. A piston is positioned in the cylinder between the pair of passages and is slidable in response to hydraulic pressure in the cylinder on each side of the piston. A piston rod connects the piston to a joint which is connected to the trunnion lever of the hydrostatic transmission. A pedal position sensor (108) provides electrical signals to an electronic controller (110) that selectively actuates the pair of pressure control valves.
