Abstract
Abstract The systems shut-down handle for motorized apparatus comprises the housing; a throttle assembly having a pivotally mounted handle lever juxtapositioned about the grip of a handlebar of the apparatus, the throttle lever being connected to the apparatus throttle cable; and a brake and shut-down assembly having a brake lever pivotally mounted to the housing about the grip and is disengaged when the lever is depressed adjacentely about the handlebar grip and engages the brake when the lever is released and pivoted away from the grip. The lever is provided with means for actuating a cut-off switch which may break the electrical circuit controlling ignition in the engine. The brake and shutdown assembly may further include an idling trigger which may retain the brake lever adjacent the grip to disengage the brake and maintain the engine circuit.
