  • ELECTROHYDRAULIC ACTUATOR FOR HYDROSTATIC TRANSMISSION
    Publication number: 20190128411
    Abstract: An electrohydraulic actuator for a hydrostatic transmission includes a pair of pressure control valves 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 provides electrical signals to an electronic controller that selectively actuates the pair of pressure control valves.

  • Zero turning radius mower
    Patent number: 10005358
    Abstract: A zero turning radius mower has an internal combustion engine mounted transversely on a pair of longitudinal frame members behind an operator seat and a pair of rear drive wheels. The engine rotates a flywheel on a horizontal axis perpendicular to the longitudinal frame members. A gearbox is mounted to one of the longitudinal frame members, with a horizontal input shaft driven by the engine and a vertical output shaft engaging one or more rubber belts. The same rubber belts drive a pair hydrostatic transmissions for the pair of rear drive wheels and a plurality of rotary mower blades under a mower deck.
