SOLUTION: The combine harvester is equipped with the winnower fan 26 for carrying out wind selection by enabling cooling wind after cooling an engine to be sucked, a means for detecting the amount of reaped grain culms, a sucking-regulating means for regulating the sucking by the winnower fan 26, a winnower fan case 56 covering the winnower fan 26 and forming a discharging opening 57 thereof, a wind direction-changing means for changing the direction of the discharged wind discharged from the discharging opening 57, and a controller 165. The combine harvester also has a wet material mode-switching means to enable the sucking-regulating means and the wind direction-changing means to be changed according to the switching of the wet material mode-switching means and the amount of the grain culms.
