ABSTRACT:
A safety start system for lawn and garden equipment in which a single safety switch completes the starting circuit of the power source by responding to the disengaged condition of both the main clutch and the implement clutch of the machine. The starting circuit is completed in direct response to the operator's moving the implement clutch handle to its disengaged position thereby permitting a resilient actuating member to close a safety switch and complete the circuit. The circuit is interrupted upon his engagement of the main clutch through a release of the clutch pedal which changes the deflection point of the resilient actuating member from the safety switch to linkage which is connected to the clutch pedal mechanism.
