Abstract: A work implement has an internal combustion engine that drives a tool of the work implement via a clutch. The clutch has at least one driving element which is operatively connected to the internal combustion engine and at least one output element which is operatively connected to the tool. The internal combustion engine has a starting device with a starting position and an operating position. To avoid unintentional rotation of the output element when starting the internal combustion engine, the work implement has a blocking device with a detent pawl. In an actuated position, the detent pawl projects into the movement path of the output element, limiting the rotation of the output element. In an unactuated position, the detent pawl releases the output element. The starting device has an actuating device which, in the starting position, keeps the detent pawl in the actuated position.

Abstract: An engine starting device includes a roller selectively engageable between the crankshaft of an engine and an arbor. The roller causes the arbor to rotate in a loading direction in response to rotation of the crankshaft. Rotation of the arbor loads an elastic member. A locking mechanism, such as a ratchet wheel and pawl may be used to keep the elastic member loaded until it is desired to startup the engine. Engine startup is initiated by disengaging the pawl from the ratchet wheel and permitting the elastic member to unload. A pinion gear is mounted on a helically threaded portion of the arbor and moves axially along the helically threaded portion in response to unloading of the elastic member. The pinion gear engages teeth on the flywheel and causes the flywheel to rotate in a starting direction under the influence of the unloading elastic member.

Abstract: An internal combustion engine includes an engine housing, a crankshaft supported within the engine housing for rotation with respect to the engine housing, and a flywheel fixedly mounted to the crankshaft and rotatable with the crankshaft in a starting direction to start the engine. A coil spring has an outer end fixedly interconnected with respect to the engine housing, and an inner end. A unidirectional clutch has a portion connected to the inner end of the spring. The unidirectional clutch is characterized by an interference condition in which the unidirectional clutch couples the inner end of the spring to the flywheel such that the flywheel and crankshaft may be rotated in the starting direction in response to unloading of the spring. The unidirectional clutch is also characterized by a non-interference condition in which the inner end of the spring is uncoupled from the flywheel. An input assembly is interconnected with the spring and selectively movable into contact with flywheel to load the spring in response to rotation of the flywheel. A locking mechanism selectively prevents the spring from unloading, and at least one manual actuator is actuable to disengage the locking mechanism from the spring to enable unloading of the spring.
