Abstract
An engine-driven working machine including a controller by which a time period until the rotation speed limitation mode is canceled can be shortened. After a throttle valve is moved to a fully-closed position by an operation to allow the engine to finish the fast idling state and while the engine is transited to an idling state, the controller cancels the rotation speed limitation mode by detecting an event in which a cycle period of rotation speed variations of the engine is longer than a cycle period of rotation speed variation in the fast idling state.
