摘要： 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.

摘要： A safety system for a riding lawn mower that prevents powered operation of a PTO driven implement while in reverse unless an override switch is “ON”. The override switch may be a sustained action two position switch and the PTO driven implement may be a lawn mower blade. In one embodiment, the override switch does not allow the engine to start if the override switch is on. In one embodiment, the override switch cooperates with an operator presence switch to prevent operation of the PTO driven implement when the override switch is on and the operator is not present.

摘要： Control method and apparatus for a lawn mower or a lawn and garden tractor that includes a programmable controller for monitoring a mower/tractor status. The controller includes an interface for monitoring inputs relating to a status of the mower/tractor and controlling outputs that regulate operation of the mower/tractor. The controller also includes a memory for storing instructions to implement a control over operation of the mower/tractor. The instructions include instructions for determining a safety status condition based on sensed inputs and outputting a signal from the interface of the controller that inhibits operation of a lawn mower/tractor motor or engine in response to a determination of the safety status condition.
