A lawn mower is provided with a control mechanism for a propel drive clutch. The control mechanism includes a deadman control lever which operates to hold a clutch-control lever in a clutch-engage position only when the deadman control lever is held in a lever-holding position. Upon release of the deadman control lever, the latter automatically moves to a lever-release position which permits the clutch-control lever to automatically move to a clutch-disengage position.

In combination with a self-propelled, walk-behind implement having a main frame and an upwardly and rearwardly extending guide handle fixed to the frame, a two-stage control mechanism adapted for operating a normally spring-disengaged traction drive clutch, comprising: a clutch control lever, in the form of a flat bar, adapted for connection to the clutch and pivotally mounted on the handle for movement along a predetermined path between clutch-release and clutch-engage positions; a deadman control lever including a cantilevered spring metal strap bent to form a detent having a ramp at its free end, the deadman control lever being pivotally mounted on the handle for movement between a lever-release position, wherein the spring metal strap is clear of said path, and a lever-holding position wherein the ramp of the spring metal strap is disposed in the path and blocks movement of the clutch control lever from its clutch-engage position, whereby the clutch control lever may be moved to its clutch-engage position after the deadman control lever is moved to its lever-holding position by engaging the ramp and deflecting the spring metal strap; and biasing means connected between the handle and the deadman control lever and urging the latter towards its lever-release position.
