PROBLEM TO BE SOLVED: To provide a combine harvester that can restrain a driving load of a feed chain.SOLUTION: A combine harvester 1 comprises a feed chain driving mechanism 9 and a power transmission mechanism 11. The feed chain driving mechanism 9 comprises a driving sprocket 94, a driven sprocket 95b, and a lower chain rail 92 on which a feed chain 96 is laid. The lower chain rail 92 extends linearly from a lower edge of the driving sprocket 94 to a lower edge of the driven sprocket 95b. The power transmission mechanism 11 comprises a counter shaft 11 and a hydraulic type continuously variable transmission 112. The counter shaft 111 is provided with a counter pulley 120. An input shaft 112a of the hydraulic type continuously variable transmission 112 is provided with an input pulley 121 to which driving force is transmitted from the counter pulley 120 and transmitting pulleys 137a and 137b for transmitting the driving force to a separation part 6. |
