PROBLEM TO BE SOLVED: To perform direction control of a combine harvester on a field of a rough planting method with e.g. 30 cm intrarow spacing in the crosswise and longitudinal directions. SOLUTION: A direction sensor (21) capable of detecting approaching state to reaping object grain culm is set on a reaping and transferring part (6) to perform direction control output to operate a machine body based on detection results of the direction sensor (21), and a control part (26) performing row reaping/lateral reaping-determination control of a reaping object grain culm row is formed, and, when a direction control switch (32) is on and the row reaping/lateral reaping-determination switch (31) is off, the control part (26) does not perform row reaping/lateral reaping-determination but perform direction control output.
