  • Mower hydraulic leak detection system
    Patent number: 11606898
    Abstract: A hydraulic leak detection system includes a leak detection switch responsive to a level of hydraulic fluid in a tank used by a hydraulic mowing circuit and a lift and lower circuit of a grass mowing machine. The system includes a controller that activates a warning indicator if the leak detection switch indicates the level of hydraulic fluid in the tank is low, but allows the hydraulic mowing circuit and the lift and lower circuit to continue operating until the lift and lower circuit reaches a fully raised position. A solenoid valve may control the level of hydraulic fluid in the tank based on temperature of the hydraulic fluid.
    Type: Grant

  • End of cut speed control system
    Patent number: 9179596
    Abstract: An end of cut speed control system includes a vehicle controller that commands a traction drive system to a reduced ground speed based on the setting of a control to a preset end of cut mode ground speed as a percentage of the mow mode ground speed. The vehicle controller changes the speed from the mow mode to the end of cut mode when a proximity sensor indicates the cutting units are raised to a cross cut position.
