PROBLEM TO BE SOLVED: To hardly have an adverse effect on a screw drive shaft even if a large load acts on a chopper drive shaft and rotation unevenness occurs.SOLUTION: A combine harvester includes a belt transmission mechanism for transmitting torque from an output shaft 51 to grain discharging screw drive shafts 59 and 61 of a thresher 3 and a chopper drive shaft 69 of a chopper 66 for finely cutting straw wastes discharged from the end of a threshing chamber through a drive belt. A first belt transmission mechanism 78 ranging from the output shaft 51 to the screw drive shafts 59 and 61 and a second belt transmission mechanism 80 ranging from the output shaft 51 to the chopper drive shaft 69 are individually arranged as the belt transmission mechanism. |
