Working machine with a combustion engine

A work apparatus has an internal combustion engine (11) that drives at least one tool of the work apparatus via a clutch (13). The clutch (13) has at least one drive element (63) in operative connection with the internal combustion engine (11) and at least one output element (51) in operative connection with the tool. The work apparatus has a starting device (39) with a starting position (42) and an operating position (35). In order to prevent unintended rotation of the output element (51) during starting, the work apparatus has a locking device (43) with a pawl (44) which, in an actuated position (46), extends into the path of movement of the output element (51) and limits the rotation of the output element (51) to less than one complete revolution, and which, in an unactuated position (47), releases the output element (51). The starting device (39) has an actuating device (45) for the locking device (43), which holds the pawl (44) in the actuated position (46) in the starting position (42) of the starting device (39).
