Work machine

A work machine comprising:

• a machine body;
• a work device attached to the machine body;
• a plurality of hydraulic actuators that drive the machine body or the work device;
• a hydraulic pump;
• a plurality of directional control valves that are connected in parallel to a delivery line of the hydraulic pump, and adjust a flow of a hydraulic fluid supplied from the hydraulic pump to the plurality of hydraulic actuators;
• an operation lever for giving an instruction to operate the plurality of hydraulic actuators;
• a machine control switch for giving an instruction to activate or deactivate a machine control function that prevents the work device from going into a preset area;
• and
• a controller that executes the machine control function in a case where the machine control function is selected via the machine control switch,
• the work machine further comprising:
• auxiliary flow rate control devices that are arranged upstream of the plurality of directional control valves, and limit the flow rate of the hydraulic fluid supplied from the hydraulic pump to the plurality of directional control valves in accordance with pressure variations at the plurality of hydraulic actuators,
• the controller is configured to,
• in a case where the machine control function is cancelled via the machine control switch, cancel limitation of the flow rate of the hydraulic fluid supplied to the plurality of directional control valves, the limitation being performed by the auxiliary flow rate control devices, and
• in a case where the machine control function is selected via the machine control switch, cause the auxiliary flow rate control devices to limit the flow rate of the hydraulic fluid supplied to the plurality of directional control valves.
