PROBLEM TO BE SOLVED: To enhance efficiency of operations of a combine, such as a grain discharge operation, a threshing and sorting operation by promoting downflow of grains in a grain storage device and a threshing device even when objects to be threshed such as grains, straws and the like are wet. SOLUTION: In the combine, a first means is constituted to promote downflow of stored grains in the grain storage device 4 toward a spiral conveying device 28 by heating the bottom surface 31 of the grain storage device 4 with exhaust of an engine E mounted on a machine body 1, a second means is constituted to raise temperature of grading wind blown from a wind-tunnel 45 by heating the wind-tunnel 45 of the winnowing fan 22 of a threshing device 3 with the exhaust of the engine E mounted on the machine body 1 and a third means is constituted to promote downflow of the objects to be threshed on a first grain flow plate 54 toward a first transport trough 52 by heating the first grain flow plate 54 with the exhaust of the engine E mounted on the machine body 1.
