Abstract
A gasoline powered machine, shown in the form of a lawn mower, having a gasoline engine, and a mower deck for a housing, and a mower handle, and ground engaging wheels. The engine has the usual electric circuitry connected thereto, and two electric switches are connected with the circuitry for grounding the circuit and thereby stopping operation of the engine when the switches are not being operated, and that is when they are then in a normally-closed position. Therefore, the operator must be in physical contact with either of the two switches to maintain either one in an open position in order to have the gasoline engine operating.
