Abstract

See full text

A lawn mower includes an internal combustion engine, an electric motor configured to start the engine, a blade driven by the engine, and an assembly for stopping at least one of the blade and the engine. The assembly includes a brake mechanism, a release mechanism movable to an engaged position to release the brake mechanism, an interlock configured to selectively prevent the release mechanism from moving to the engaged position, and an interface allowing an operator to release the interlock to allow the release mechanism to move to the engaged position. The lawn mower further includes a switch actuated by the release mechanism and a control module coupled to the switch so that the switch provides a signal to the control module when the release mechanism is in the engaged position and the control module turns on the electric motor in response to the signal to start the engine.
