ABSTRACT:
A lever assembly including a clutch actuator mechanism is located within a housing on a handle assembly of a self-propelled machine for selectively activating and deactivating respective clutches for applying power from a prime mover, such as a gasoline engine, to at least one of a set of drive wheels for propelling the machine over a work surface and for applying power to one or more cutting elements, which may be, for example, a blade of a self-propelled lawn mower. Depending upon the sequence of actuation of two clutch activating control levers, the self-propelling drive wheels, cutter element, or both can be selectively actuated so that an operator may, for example, cause the lawn mower to travel across a surface without power being applied to the cutting blade.
