摘要： A method and apparatus for enabling reverse mow condition in a tractor comprises a switch assembly having an ignition switch that is rotatable through a plurality of positions, a housing for supporting the ignition switch, and an actuator movably located in the housing. The enabling of a reverse mow condition is achieved by displacing the actuator from a rest position to two separate and distinct positions.

摘要： A controller including a controller input coupled to an engine magneto for monitoring tractor engine operation by monitoring a change in magneto signal thereby determining if the engine is running. A power output circuit coupled to an output from the controller draws current from a tractor battery for powering an auxiliary component when the tractor engine is running and disrupts power to the auxiliary component when the tractor engine is not running to conserve battery life.

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 control system for an electrical device includes a controller that outputs an AC device enable system when one or more monitored sensors are in a proper state for operation of the electrical device. The control system may also include a sensor signal integrity checking circuit that outputs a validation signal when the sensor is one of a discrete set of acceptable sensor states. The control system may also include a current monitor that monitors the current draw of the electrical device and compares the current draw to a range of acceptable current draw levels and durations and disables operation of the electrical device when the current draw falls outside of the range.

摘要： An ignition circuit causes a magneto to continue to provide spark to an engine for a delay period after the ignition switch is switched off. After the delay period, the ignition circuit routes energy from the magneto to actuate a magneto disable switch to provide a path to ground for the magneto.

摘要： A control circuit for a lawn tractor having an engine and a power take off driven implement. The control circuit includes an inhibit circuit component for preventing operation of a power take off driven implement with the tractor in reverse. Two versions of the inhibit circuit are disclosed, one grounds an engine magneto and a second disables an electric clutch for coupling the power take off to the driven element. The circuit includes first and second override switches and an override circuit component that allows operation of a power take off driven implement while the lawn tractor is in reverse after the first and second override switches are activated in a proper order by a tractor operator.

摘要： A switch mounting assembly that adapts a switch to detect a position of a vehicle control, such as the position of a drive control actuator of a lawn and garden tractor or similar vehicle. The switch mounting assembly includes a switch support member and a lever pivotally connected to the switch support member. The switch support member mounts a switch that includes an actuator that is biased to an extended position and a may be selectively depressed to a retracted position. The lever is pivotable between a first position that allows the actuator to be biased to the extended position and a second position that depresses the actuator to the retracted position.

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： An engine with an integral actuator for a vehicle having an implement needing control. The engine includes a crank shaft, and a pump in a housing and an actuator that extends from the housing. The pump is operably connected to the crank shaft to produce a flow of fluid, such as oil, from the pump to the actuator. A valve is operably connected to the pump or the actuator to selectively move the actuator.
