Abstract
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.
Claims4
A work vehicle, comprising:
- a body frame;
- a front weight supported by a front end portion of the body frame in such a manner as to be movable in a front-back direction;
- 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;
- a turning state determiner configured to determine whether a body of the work vehicle is performing turn travel;
- and
- a position controller configured to, in response to the turning state determiner determining that the body is performing turn travel, control an operation of the drive actuator so that the front weight is at the back position.
