ABSTRACT:
A lawn mower including a blade housing supporting a prime mover which drives a cutter blade. The prime mover causes rotation of a drive shaft and a clutch driven by the drive shaft is engagable and disengagable with the cutter blade. A handle is connected to the housing and a dead man control is pivotally attached to the handle. The lawn mower further includes an arrangement operable to permit the engagement and disengagement of the clutch means by the pivotal movement of the dead man control. This arrangement includes a flexible member connecting the dead man control and the clutch and an arrangement restricting a substantial portion of the flexible member to a predetermined path along the handle. The restricting arrangement includes a pulley rotatably attached to the handle between the dead man control and the housing and the flexible member is guided around the pulley. In one embodiment, the mower is self-propelled and includes wheels connected to the housing to support travel of the housing over the ground. The mower also includes a mower propelling arrangement engagable with the wheels. An upper handle is movably attached to a guiding handle and a link connects the upper handle to the mower propelling arrangement. The link is movable in response to movement of the upper handle to cause engagement of the mower propelling arrangement. The self-propelled lawn mower has the dead man control movably attached to the upper handle and the pulley has a periphery generally adjacent the attachment of the upper handle to the guiding handle so the upper handle and dead man control can be operated independently.
