PROBLEM TO BE SOLVED: To easily perform automatic traveling even when automatically traveling a traveling vehicle and a towing vehicle connected to the traveling vehicle along a planned traveling route. A work vehicle has a connecting portion for connecting a towing vehicle and is capable of traveling along a planned travel route, and a relative angle between the connecting portion of the traveling vehicle and the towing vehicle connected to the connecting portion. And an automatic traveling control unit that controls automatic traveling in the traveling vehicle based on the planned traveling route.
