Abstract
A work machine capable of reliably ejecting loads loaded in a bucket is provided. A travel sensor detects a state of travel of a travel unit. A work implement posture sensor detects a posture of a work implement. An object sensor detects an object around a main body. A controller provides a command to drive a work implement actuator based on detection values from the travel sensor, the work implement posture sensor, and the object sensor. The controller recognizes a loading target into which the loads in the bucket are to be loaded, based on detection of the object. The controller controls the work implement actuator and the travel unit such that the bucket is set to a full dump state while a feature point of the bucket is located above the loading target and such that the travel unit travels rearward with the full dump state being maintained.
