ABSTRACT:
A control apparatus for the blade clutch assembly of a walk-behind powered lawnmower is provided that incorporates a "dead man" feature along with a two-step procedure for engagement of the clutch. The control apparatus includes a shiftable bail, a cable having an engageable end portion, a two-armed coupling mechanism responsive to shifting of the handle, and a pivotally mounted cam for engaging and disengaging the coupling mechanism from the cable end portion. The coupling mechanism is positioned in cable end portion engaging alignment by shifting of the handle to a first position, and is maintained in engagement with the cable end portion by one surface of the cam as the handle and cable are shifted to second positions. The cable is biased by a coil spring to its first position, and upon release of the handle the cable will shift from the second to the first position. A second surface of the cam engages the coupling mechanism for disengagement of the coupling mechanism from the cable end portion when the cable shifts to its first position. Reengagement of the cable end portion by the coupling mechanism can only be accomplished by the two-step procedure described above.
