Work machine

A work machine comprising:

• a multijoint type work implement;
• a plurality of hydraulic actuators that drive the work implement;
• an operation device that gives instructions on motions of the hydraulic actuators;
• a notification device that notifies an operator of operation support information;
• and
• a controller having a notification control section that exercises control as to whether to notify the operator of the operation support information in accordance with a distance between a predetermined target surface, out of a plurality of discretionally set target surfaces, and the work implement, wherein
• the work machine further comprises a current terrain profile acquisition device that acquires a position of a current terrain profile to be worked by the work implement,
• the controller having a processor and a memory, the processor configured to:
• determine a vertical position relationship between the current terrain profile and a target surface closest to the work implement and a vertical position relationship between the current terrain profile and a target surface adjoining the target surface closest to the work implement in a motion direction of the work implement by comparing the position of the current terrain profile, a position of the target surface closest to the work implement, and a position of the target surface adjoining the target surface closest to the work implement in the motion direction of the work implement, and
• change content of the operation support information in accordance with a result of the determination.
