The purpose is to provide a working vehicle such that, when a reverse switch coupler is detached, or when a wire connecting a reverse switch to a control device is disconnected, driving of a PTO shaft can be reliably prevented and reliability of the reverse switch can be improved. In a tractor, a reverse switch includes a normally closed type first contact, and a normally open type second contact that is switched in association with the first contact. When an input voltage from the first contact is higher than a set voltage, and when the input voltage from the first contact is lower than the set voltage and an input voltage from the second contact is equal to or lower than the set voltage, a control device controls the actuator such that the PTO clutch is disconnected.
