  • Patent number: 7891448
    Abstract: Control circuits for a riding lawn mower providing an override condition for selectively allowing the cutting blades of the lawn mower to operate when the vehicle is traveling in reverse. The circuits incorporate a multi-position ignition switch, an override switch, a vehicle reverse switch, a PTO switch and a park brake switch. In one aspect of the invention, the control circuits disable the engine when the vehicle is placed in reverse with the PTO engaged and without the override condition having been established. In another aspect of the invention, an electric PTO clutch is disabled when the vehicle is placed in reverse with the PTO engaged and without the override condition having been established. The override condition is terminated when the ignition switch is moved away from the override position, or when the operator activates the park brake switch.
