ABSTRACT:
In a walk-behind rotary lawn mower powered by a gasoline engine, two pushbutton-type switches are so connected in the engine ignition circuit that at least one must be actuated for the engine to run. One switch comprises a dead-man control actuated by gripping the mower guide handle. The other is actuated by a treadle so located on the mower deck as to be depressed by one foot of a person who has his other foot in a safe position and who is operating the engine rope starter in a natural, convenient manner. Depression of the treadle also actuates a brake that prevents the mower from rolling.
