PROBLEM TO BE SOLVED: To settle problems that as a radiator is opened by vertical axis rotation so, when the rotation angle of the radiator is made to be large, the maintainability of other elements is deteriorated, and, as the rotation angle of the radiator is enlarged so each hose length of a cooler becomes longer.SOLUTION: There is provided a combine harvester, which is characterized in that a reaping device 4 is set at the front side of a traveling device 2, a threshing device is set at the upper one side of the traveling device 2, a grain tank 5 is set at the upper other side of the traveling device 2, an engine 12 driving the traveling device 2, the reaping device 4 and the threshing device is installed, a cooling fan 13, a shroud 17 covering the cooling fan 13 and a cooler F are set at the outside of the engine 12, a belt 27 transmitting driving force from the engine 12 to a discharge device 25 of the grain tank 5 is set at the inside lower side of the cooler F, and the cooler F and the shroud 17 are pivoted rotatably around a rotation support S in a front-back direction on an upper side.
