PROBLEM TO BE SOLVED: To provide a harvesting machine that enables uniform harvesting work to proceed over the entire circumference of an unworked area. SOLUTION: The harvester creates an unworked map creation unit that creates unworked map data indicating an unworked area, and, based on the unworked map data, parallels each side of a polygon indicating the outer shape of the unworked area. The first traveling pattern in which the work traveling route is sequentially clockwise in the spiral target traveling route that is composed of the working traveling route and the turning traveling route that connects the two traveling routes with the direction change of the machine body, or sequentially in the counterclockwise direction. And a target travel route setting unit that sets using the second travel pattern for performing work travel or both the first travel pattern and the second travel pattern.
