PROBLEM TO BE SOLVED: To improve accuracy of various controlling operations and evade the lowering of working efficiency in threshing works. SOLUTION: This combine harvester is provided with the following: a threshing apparatus 3 comprising a threshing chamber 11 axially mounting a threshing cylinder 10, a winnowing chamber 15 placed below the threshing chamber 11, a blowing winnower 13 for sending air to the winnowing chamber 15 and a swinging selection shelf 16 which is placed in the winnowing chamber 15 and selects grains by the blowing and swinging of the blowing winnower 13, a near infrared moisture meter 26 for detecting the moisture value of one or both of the grains and grain culms in the threshing apparatus 3, and a grain sensor 27 placed on the terminal side of the winnowing chamber 15 and detecting the grains discharged outside the machine. The number of revolutions of the blowing winnower 13 and the interval of sheaves 19 of the swinging selection shelf 16 are controlled in accordance with the moisture values detected by the near infrared moisture meter 26 and the waste dust loss detected by the grain sensor 27.
