Abstract

Control system (2) for an outdoor power equipment unit includes a pivotal control member (10) having a pivotal traction drive link (20) for actuating a traction drive of the unit and a pivotal clutch link (22) for actuating an active element of the unit. A latch (40) rotatively couples the clutch link (22) to control member (10) only when control member (10) has first been moved from a neutral position to a cocked position. Rotation of control member (10) from the cocked position towards the fully engaged position then rotates the clutch link (22) to actuate the clutch. The traction drive link (20) can be operated either alone or in combination with the clutch link (22). Any rotation of control member (10) from its neutral position towards its fully engaged position will rotatively couple the traction drive link (20) thereto to actuate the traction drive.
