ABSTRACT:
A self-propelled walk-behind mower includes blade and traction drive clutch control levers associated with a deadman control lever which operates a pair of lever latches such that it is necessary for the deadman control lever to be held depressed against the guide handle of the mower to allow the blade and traction drive control lever to be held in respective clutch-engage positions, the control levers being biased to automatically return to respective clutch-disengage positions once the deadman control lever is released. A pair of latch release levers are respectively operative to selectively actuate one or the other of the lever latches so as to permit one or the other of the blades and traction drive control clutches to automatically return to its clutch-disengage position when the deadman control lever is held depressed against the operator's handle.
