PROBLEM TO BE SOLVED: To suppress a decrease in work efficiency. A work vehicle according to an embodiment is provided on a traveling vehicle body, a work machine that is mounted on a rear portion of the traveling vehicle body so as to be able to move up and down, a control unit that controls lifting and lowering of the working machine, and a rear portion of the traveling vehicle body. A rear sensor that detects an object existing behind the traveling vehicle body and the height at which the work machine is raised and the height at which the rear sensor detects the work machine are stored as a regulated height, and the height of the work machine is remembered during work. And a control unit that regulates the rise of the working machine so as to be equal to or lower than the regulated height.
