Abstract
A hedge trimmer includes a motor and a cutting mechanism driven by the motor. A clutch mechanism is interposed between the motor and the cutting mechanism. A first and a second handle are provided to be grasped with both hands of an operator. A clutch control mechanism is provided for connecting and disconnecting the clutch mechanism. The clutch control mechanism includes a first and a second switch lever which are associated with the first and second handles, respectively, and which are operable by the operator between a first and a second position, respectively. A pin is operably connected to the first and second switch levers and is movable between a connecting position for connecting the clutch mechanism and a disconnecting position for disconnecting the clutch mechanism. Biasing members serve to hold the pin at the disconnecting position when at least one of the first and second switch levers are at the first position. The biasing members permit movement of the pin from the disconnecting position to the connecting position when both the first and second switch levers are moved from the first position to the second position.
