<P>PROBLEM TO BE SOLVED: To provide a harvester which has a waste-exhausting portion for exhausting wastes from a threshing portion and a separating portion outside the harvester, and can improve the separation performance of the separation portion in spite of the changes of threshed amounts and separated amounts. Ž<P>SOLUTION: In the waste-exhausting portion for exhausting wastes from the threshing portion and the separating portion outside the harvester, large wastes such as exhausted straws are exhausted outside the harvester in states treated with exhausted straw-treating member 74 disposed in a straw-exhausting route 71 through the straw-exhausting route 71 placed on the front side of an air-exhausting route 72. Meanwhile, small wastes such as exhausted dusts are exhausted outside the harvester through the air-exhausting route 72 placed on the rear side of the straw-exhausting route 71 by the forceful feeding action of a separation fan 52 and by the suction action of a suction fan 73 disposed in the air-exhausting route 72. The suction amount of the suction fan can be adjusted. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
