WORK VEHICLE AND CONTROL METHOD FOR WORK VEHICLE

A work vehicle includes a power transmission device that transmits power input to an input shaft to an output shaft via a clutch mechanism, a forward-reverse operation device that is operated to change a state of a traveling device between a forward state, a neutral state, and a reverse state, and a control device. The control device includes: an operation signal acquisition unit that acquires an operation signal generated by an operation of the forward-reverse operation device; a torque reduction command unit that outputs a torque reduction command for reducing a torque of the output shaft in a state where a first clutch among a plurality of clutches of the clutch mechanism is engaged, before a specified time elapses from a time point at which the operation signal for changing to the neutral state is acquired in a state where the first clutch is engaged; a clutch control unit that outputs a release command for releasing the first clutch after the specified time elapses; and a power control unit that outputs a control command for controlling the power transmission device so that a rotation speed of an input-side element of a second clutch to be engaged next coincides with a rotation speed of an output-side element of the second clutch in a state where the first clutch is released.
