PROBLEM TO BE SOLVED: To obtain reaping performance of a combine harvester corresponding to high speed operation by building a reaping speed change gear in a transmission pathway to a reaping part (8) without changing existing transmission shape to the reaping part (8) and its peripheral structure. SOLUTION: This combine harvester is equipped with a reaping speed change gear (77) for carrying out transmission by always engaging a pair of gears (105) and (106) having high and low speeds with each other and running idle on an output shaft (96) to a reaping part (106) and binding a clutch (114) rotating together with the above output shaft (96) to either one gear (105) or (106). The reaping speed change gear (77) is built into input side end of swinging and sorting panel-driving shaft (76) pivotally supported on front wall of a threshing part (4). The input shaft (95) from a winnower shaft (85) is installed in the outer periphery of the above output shaft (76) and always bound to either one gear (105) and the other gear (106) is always bound to the above swinging and sorting panel-driving shaft (76) to carry out transmission to the reaping part (8) and the swinging and sorting panel-driving shaft (76).
