Abstract

In a work machine, a control unit controls a pilot control valve for controlling the opening area of a first direction switch valve in executing the combined operation to be less than or equal to that in executing a single operation. The combined operation represents an operation of simultaneously operating first and second actuators. The single operation represents an operation of operating only the first actuator. Further, the control unit determines the opening area of the first direction switch valve in the combined operation based on a hydraulic pressure detected by a hydraulic pressure detector unit.
