<P>PROBLEM TO BE SOLVED: To provide a combine harvester obtained by improving maintenance operability of a reaping device 3 and a threshing device 5 while enabling a driving mechanism (a reaping input belt mechanism) of the reaping device 3 to be simply constituted. Ž<P>SOLUTION: The combine harvester is constituted so that the reaping device 3 may be lifted and lowered by allowing the reaping device 3 to be turned around a horizontal shaft 4a, and may be horizontally moved by allowing the reaping device 3 to be turned around a vertical shaft 150. A machine body-side input shaft 178 for transmitting a reaping driving power from a transmission case 26 is arranged in a traveling machine body 1, and a moving-side input shaft 45 for transmitting the reaping driving power to the reaping device 3 is arranged in the reaping device 3. The reaping device 3 has a structure in which the moving-side input shaft 45 is connected to the machine body-side input shaft 178 through a gear mechanism 185 detachable by the horizontal movement of the reaping device 3 around the vertical shaft 150. A PTO speed-changing mechanism 110 for switching the driving speed of the reaping device 3, and a PTO constant rotation mechanism 111 for operating the reaping device 3 at a prescribed constant rotary speed are arranged in the transmission case 26.
