Engine speed controller of work machine
According to the present invention, when specific work in which the operating rate of an operating device is reduced from a state in which an engine is kept at an idling speed, the discharge flow rate of a main pump returning to a tank is reduced. The present invention is provided with a main controller (20) that is capable of controlling the speed of an engine (11) to a normal work speed at which a work implement such as a boom (4) can do normal work, and that controls the speed of the engine (11) to an idling speed which is a lower speed than the normal work speed when the operating device has returned from an operating position to a neutral position; and the main controller (20) performs a control process for bringing the speed of the engine (11) to a specific work speed which is a speed higher than the idling speed and lower than the normal work speed upon detection that the specific work, which is performed at a low operating rate of the operating device such as a boom operating device (16), is carried out in a state in which the speed of the engine (11) is maintained at the idling speed.
