PROBLEM TO BE SOLVED: To provide a combine harvester automatically stopping the driving of an unloading device with a grain sensor without automatically stopping the driving of the unloading device during maintenance and inspection. SOLUTION: The combine harvester includes: a storage device (5a) installed for temporarily storing grains threshed with a threshing device (3); the unloading device (6) installed for unloading the grains in the storage device (5a) to the outside of the machine; the grain sensor (19) installed for detecting the grains stored at a low position in the storage device (5a); and an unloading controller (67) installed for automatically stopping the driving of the unloading device after the passage of a prescribed time from the time when the grains are not detected with the grain sensor (19) according to a decrease of the grains in the storage device (5a) when the unloading device (6) is driven and operated in a state that the grains are detected with the grain sensor (19), and continuing the driving of the unloading device (6) during a period when the driving operation is carried out when the unloading device (6) is driven and operated in a state that the grains are not detected with the grain sensor (19).
