A work vehicle includes: a body frame; a front weight at a front end portion of the body frame; a support mechanism supporting the front weight in such a manner that the front weight is movable in a front-back direction relative to the body frame; and a drive actuator configured to move the front weight in the front-back direction relative to the body frame between (i) a back position, at which the front weight is close to the body frame, and (ii) a front position, at which the front weight is far from the body frame.
