摘要：
A safety system for engine powered machinery having a fuel cut functionality to promote more rapid shutdown of the rotating parts of the engine powered machinery. In one aspect, the system is implemented as a wiring harness disposed exclusively on the engine which simultaneously disables one or more ignition coils and prevents a fuel-air mixer from supplying a mixture of air and fuel to the engine upon activation of a safety switch. In alternate aspects, the system further comprises a stator brake which is activated by the safety switch to provide additional braking torque on the engine. These features bring the machinery to a rapid halt, further enhancing safety.
