<P>PROBLEM TO BE SOLVED: To provide a combine harvester capable of preventing output efficiency of an engine 70 for driving a traveling section 2 or a grain threshing device 5 and the like from deterioration by suppressing abnormal temperature rise of a fuel supplied to the engine 70. Ž<P>SOLUTION: In the combine harvester, a common rail 120 is arranged on the engine 70 mounted on a travel machine frame 1 and the traveling section 2 or the grain threshing device 5 is driven by output of the engine 70 to which the fuel is supplied from a fuel tank 118 via a fuel pump 116. The combine harvester includes a structure in which fuel pipes 137, 139 for connecting the fuel pump 116 or a common rail 120 with the fuel tank 118 are arranged. The fuel pipes 137, 139 are formed in a plurality of routes and the fuel pipes 137, 139 of the plurality of routes are alternatively selected by a route switching body 136 so that the fuel pump 116 or the common rail 120 is communicated with the fuel tank 118.
