Work vehicle and control method for work vehicle

A work vehicle comprising:

• an input shaft that is connected to an engine;
• an output shaft that is connected to a traveling device;
• a power transmission device that transmits power input to the input shaft to the output shaft via a clutch mechanism;
• a forward-reverse operation device operated to change a state of the traveling device between a forward state, a neutral state, and a reverse state;
• and
• a control device,
• wherein 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.
