Abstract
A hydraulic excavator including a controller that calculates the positional relationship between a bucket and a target surface and a display device that displays the positional relationship between the bucket and the target surface includes an actuator state sensor that detects the pressure of a hydraulic cylinder. The controller calculates the velocity of the bucket based on the position of a work implement and the operation amount of an operation device and changes the contents of informing by the display device according to the velocity of the bucket, the distance between the bucket and the target surface, and the pressure of the hydraulic cylinder. The display device displays the contents of informing changed by the controller.
