A lawn mower has an engine coupled by a transmission to drive wheels and by a belt drive to cutter blades. A cutter blade clutch lever is coupled to the belt drive and a shift lever is coupled to the transmission for respectively shifting the transmission and belt drive between neutral and drive positions. Safety interlock levers are mounted adjacent the lawn mower handles and each has a hand grip which is arcuate in cross section and engageable with and complementary to the mower handle hand grips. Each safety interlock hand grip is mounted on a control rod which is pivotable from a first position to a second position wherein the hand grips are located beneath and nestled against the mower handle hand grips. The shift lever, cutter blade clutch lever and safety interlock levers are all interconnected with the engine ignition system in such a manner that if the safety interlock levers are released when the shift lever and/or the clutch lever are in their drive positions, the ignition system will be short-circuited so that the engine will be stopped.
