Abstract
An engine powered rotary lawn mower has a brake which upon being engaged stops the engine crankshaft and the cutter blade fixed thereto. A deadman control on the handle of the mower, upon being moved partway to the 'run' position in which it must be held to enable operation of the mower, disengages the brake. A manually activated gravity deactivated latch holds the deadman control in brake-off position to enable starting the engine, until the deadman control is moved all the way to the 'run' position whereupon gravity deactivates the brake.
