Abstract
A combine harvester includes a control device configured to function as a travel route creation unit, an automatic drive control unit, a course movement unit, and a course correction unit. The travel route creation unit creates, in a yet-to-be-reaped area of a field, a travel route that includes parallel first and second straight-line courses. The automatic drive control unit performs control on automatic driving and automatic reaping based on the travel route. While automatic reaping travel is conducted on the first straight-line course, the course movement unit modifies the travel route by moving the first straight-line course in a direction intersecting with the traveling direction. When movement of the first straight-line course results in movement of the first straight-line course in one direction, the course correction unit corrects a portion of the second straight-line course toward the same one direction.
