ABSTRACT:
A control lever assembly for a self-propelled lawn mower including a first control lever for selectively connecting and disconnecting a first clutch operatively coupled between a prime mover and wheels, a second control lever for selectively connecting and disconnecting a second clutch operatively coupled between the prime mover and a grass-cutting blade, and an engagement element mounted on the second control lever and engageable with the first control lever to cause the second control lever to be moved in a direction to connect the second clutch when the first control lever is moved in a direction to connect the first clutch. The control lever assembly also includes a mechanism for moving the engagement element between an operative position in which the engagement element is engageable with the first control lever and an inoperative position in which the engagement element is held out of engagement with the first control lever. With this arrangement, the lawn mower can be propelled while stopping the blade at rest against rotation as desired.
