摘要： An engine ignition shutdown module includes a voltage regulator circuit connected to a key switch, and a pair of isolated MOSFET driver circuits connected to the voltage regulator circuit. Each MOSFET driver circuit charges a capacitor while the key switch is in a run position and the interlock switches are closed, and each capacitor discharges through a resistor for a time delay period once the key switch is moved from the run position to an off position or at least one of the interlock switches are opened. A pair of high voltage output MOSFET transistors are switched on while the capacitors discharge and provide an output to a magneto ignition for the time delay period.

摘要： 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.

摘要： 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.

摘要： A riding greensmower clean-up pass speed control system reduces the maximum ground speed if a clean-up pass control is actuated. The reduced maximum ground speed is adjustable using a display. The maximum ground speed is increased to the previous ground speed each time the plurality of grass cutting reels are raised after the clean-up pass.
