PROBLEM TO BE SOLVED: To provide a work machine that can flexibly regulate the flow rate and pressure of hydraulic fluid flowing through an attached end attachment.SOLUTION: A work machine 1 comprises a crusher 92 driven by an end attachment drive actuator 20, a relief valve 220 arranged between a control valve 17 and the end attachment drive actuator 20, and a controller 30 for regulating a relief pressure by supplying a current to the relief valve 220. The controller 30 stores a corresponding relationship between the flow rate and pressure of hydraulic fluid flowing through the end attachment drive actuator 20 and a current supplied to the relief valve 220. When values of the flow rate and pressure are input through a setting unit 60, the magnitude of the current is selected, and the relief pressure of the relief valve 220 is regulated depending on the selected magnitude of the current. |
