Abstract: A hydrostatic transmission control system includes a controller that monitors inputs for shifting a transmission of a tractor to a different range gear; determines if an engine on the tractor is operating in a desired and acceptable shift range based on a sensed speed and a load of the engine, and determines if a hydrostatic transmission on the tractor is operating in a desired and acceptable shift range based on a sensed load and a speed of the hydrostatic transmission. If the controller determines the engine and the hydrostatic transmission are operating in the desired and acceptable shift range, the controller commands an oncoming clutch to ramp up and an off going clutch to ramp down, and synchronizes speeds of the engine and the hydrostatic transmission.

Abstract: A golf course implement lift system includes a global positioning system for mapping a plurality of obstacles on a golf course, and an electro-hydraulic three point hitch with a towed implement attached thereto. The electro-hydraulic three point hitch is raised when the global positioning system detects the towed implement is approaching one of the plurality of obstacles.

Abstract: Embodiments of an intelligent hinged boom excavation system include a hinged boom assembly terminating in an excavation tool, an electro-hydraulic (EH) actuation subsystem, and boom assembly tracking sensors providing tracking data indicative of excavation tool movement. A controller architecture is operable in an excavation depth limiting mode in which the controller architecture: (i) tracks a current position of the excavation tool relative to a virtual excavation floor utilizing the tracking data provided by the boom assembly tracking sensors; (ii) determines when an operator-commanded movement of the hinged boom assembly will result in breach of the virtual excavation floor by the excavation tool; and (iii) when determining that an operator-commanded movement of the hinged boom assembly will result in breach of the virtual excavation floor, controls the EH actuation subsystem to modify the operator-commanded movement in a manner preventing breach of the virtual excavation floor by the excavation tool.

Abstract: A remote tractor control system with a hand held remote control unit having an enable button that when actuated sends signals from a plurality of command buttons on the hand held remote control unit to a three point hitch controller, a transmission controller and an engine controller on a tractor. When not actuated, a rear switch module may be used to raise and lower the three point hitch or creep in forward or reverse, while the hand held remote control unit may display information about tractor condition from the engine controller.
