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 digital engine operating time measuring apparatus for an internal combustion engine. The apparatus is powered by a magneto of the engine and accumulates engine operating time only when the engine is operating. The apparatus includes power regulation circuitry including a pair of terminals coupled to the engine magneto. The power regulation circuitry converts a time varying electrical signal generated by the magneto when the engine is operating to a low voltage DC signal. The apparatus further includes digital circuitry coupled to an output of the power regulation circuitry for calculating accumulated engine operating time. The digital circuitry is powered by the low voltage DC signal of the power regulation circuitry and only accumulates engine operating time upon sensing the low voltage DC signal. The apparatus further includes a display coupled to the digital circuitry for displaying accumulated engine operating time as calculated by the digital circuitry.

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.
