PROBLEM TO BE SOLVED: To provide a combine harvester efficiently performing harvesting operations, taking out grains from a grain tank, and facilitated in high-speed running.SOLUTION: A traveling machine body travels by itself with travelling wheels 1, 2. A threshing device 10 includes: a threshing chamber in which reaped culm is put from its cut portion to its ear tip; and a threshing cylinder driven so as to rotate around the shaft core of the threshing cylinder in the longitudinal direction of the traveling machine body. The grain tank 20 is provided with: a side tank part 21 located at the side of the threshing device 10; and an upper tank part 22 located at the upper side of the threshing device 10. On the grain tank 20, a discharge screw 60 is installed while driven to rotate around the screw shaft core in the longitudinal direction of the traveling machine body, and a carrying-out auger 63 carrying out the grains from the discharge screw 60 is installed. |
