Abstract
A work machine includes a controller that executes a semi-automatic control to correct an operation amount indicated by an instruction given by operation devices. The controller is configured to make a compaction determination to determine whether or not a bottom surface of a bucket is being pressed against a ground; and to further correct an operation amount having been corrected by the semi-automatic control, such that a force that the bucket applies to the ground increases if the bottom surface of the bucket is determined as being pressed against the ground.
