PROBLEM TO BE SOLVED: To provide a combine-harvester capable of stopping an engine thereby to remove dust sucked to a dustproof net, because the dust is sucked by a dustproof net disposed at the suction port of a capacitor case during a reaping work and then that lowers the efficiency of an air conditioner.SOLUTION: A combine-harvester comprises capacitor dust removal control means (61B) for stopping capacitor cooling control means (61A) to drive reversely and to control a capacitor fan (48) and for discharging the air having been sucked from a capacitor fan side opening (51a), from a capacitor side opening (52a), thereby to remove the dust having been sucked by a capacitor fan side dustproof net (52b).SELECTED DRAWING: Figure 12
