PROBLEM TO BE SOLVED: To remove the dust on an engine cover by a simple constitution even in a combine harvester driving a cooling fan by an engine power. SOLUTION: This combined harvester 1 includes the cooling fan 10 for sucking cooling air into an engine room 7 through an air-sucking port of an engine cover 14 and a cooling fan-driving mechanism 11 for driving the cooling fan 10 by the engine power, and removes the dust on the engine cover 14 based on the reverse rotary driving of the cooling fan 10. A planetary gear mechanism 15 is provided at the cooling fan-driving mechanism 11, and the rotation power in the same direction to the crankshaft 8a of the engine 8 is transmitted to a ring gear 15a of the planetary gear mechanism 15. The cooling fan 10 is interlocked with a sun gear 15b of the planetary gear mechanism 15, and normal or reverse-rotating the cooling fan 10 is performed based on the rotary control of the carrier 15d of the planetary gear mechanism 15.
