A work vehicle includes a travelling vehicle body； a work machine mounted on a rear portion of the travelling vehicle body to be capable of being lifted and lowered； a control unit for controlling lifting and lowering of the work machine； and a rear sensor provided on the rear portion of the travelling vehicle body and configured to detect an object present behind the travelling vehicle body. The control unit may be configured to set a regulation height based on a height where the rear sensor detects the work machine while the work machine is lifted and then regulate lifting of the work machine during work in such a manner that a height of the work machine is kept less than or equal to the regulation height.
