Abstract: A combine is provided with a control device configured to function as a route generation unit, a position setting unit, a mid-work route generation unit, or a self-driving control unit. The route generation unit generates a travel route by combining a plurality of routes for an unreaped region in a field. To perform mid-work corresponding to the work amount of reaping traveling at a preset mid-work position, the position setting unit sets an interruption position at which automatic reaping traveling is interrupted to the end point of a predetermined interruption route based on the work amount. To perform the mid-work, the mid-work route generation unit generates a mid-work route extending from the interruption position to the mid-work position. The self-driving control unit controls traveling and reaping based on the travel or mid-work route.
