A work machine capable of preventing cavitation more effectively. The work machine includes a work device, a variable displacement hydraulic pump, a hydraulic actuator, a posture detector, a control valve, an operation unit, an operation detector, and a controller. The controller judges whether or not a work operation detected by the operation detector is a low-pressure operation based on posture information acquired by the posture detector, and increases the pump capacity of the hydraulic pump when judging that the work operation is the low-pressure operation.
