Abstract:
An electronically controlled speed limiting system for a turf maintenance machine includes at least one traction motor rotating a wheel. At least one hydraulic pump in fluid communication with the traction motor provides hydraulic fluid to operate the traction motor. At least one actuator in fluid communication with the hydraulic pump varies an output of the hydraulic pump. A controller in communication with the actuator commands the actuator to control the output of the hydraulic pump and thereby an operating speed of the wheel. A brake is activated by the controller if a wheel speed sensor signals the wheel is slip-spinning, to mitigate turf damage. A steering position sensor signal is used by the controller to modify brake activation during machine turns. An inclinometer signal is used by the controller to automatically reduce machine speed on inclined surfaces.
