The processor is configured to correct a motion of the boom cylinder of the attachment in such a manner as to control a lift of the rear of the traveling body with the front of the traveling body serving as a tipping fulcrum. The processor is configured to correct the motion of the boom cylinder based on a rod pressure and a bottom pressure of the boom cylinder.
