PROBLEM TO BE SOLVED: To provide a combine harvester which can switch the driving control of a feed chain on traveling or stopping the traveling in a simple structure. SOLUTION: This combine harvester has the first power transmission system A having a threshing clutch C2 disposed on the upstream side of a thresher for communicating the power of an engine to FC14 and a clutch C4 disposed in a transmission for driving a dust-discharging fan for discharging straws separated from grains outsides, the second power transmission system B disposed on the downstream side of the transmission and having a clutch C5 and a reaping clutch for transmitting a power following a vehicle speed to the FC14, a threshing lever for manually engaging/disengaging the threshing clutch and the clutch C4 to control the operation of the thresher, and a switch for engaging/disengaging the reaping clutch disposed at the tip of the threshing lever to control the operation of the reaping apparatus. When the threshing lever and the reaping switch are together switched on, the clutch C4 is disengaged. When only the threshing lever is switched on (the reaping switch is switched off) on manual threshing, the threshing clutch and the clutch C4 are switched off, and the clutches C1 and C5 are disengaged.
