PROBLEM TO BE SOLVED: To provide a combine harvester performing grain discharge work on a condition of stabilizing a running body when coordinating running body tilting control with the grain discharging work. SOLUTION: The combine harvester has a running machine body 2 supporting a discharge auger 11, running parts 4L and 4R, actuators 7L and 7R tilt-changeably tilting the machine body 2, a tilting angle detecting means 49 detecting tilting angle of the machine body 2 against the horizontal direction, and a controlling part 32 which performs tilt automatic control keeping the tilting angle of the machine body 2 to be a predetermined angle against the horizontal direction, wherein, when the conditions become to be unsatisfying in tilt automatic control, the controlling part 32 performs parallel return control returning the machine body 2 to be almost parallel to the running parts 4L and 4R, and even when the conditions are satisfied, based on raising instruction to the auger 11 detected that the horizontal turn position is receiving position, the tilting automatic control is stopped and the parallel return control is performed.
