PROBLEM TO BE SOLVED: To securely remove dust on the whole area of a dustproof net in an engine room cooling system for a combine-harvester in which an engine room apparatus such as a radiator is cooled by outer air sucked by a cooling fan driven by an engine.SOLUTION: An engine room cooling system for a combine-harvester comprises a cooling fan 12 which sucks outer air into an engine room to cool a radiator 13. When a radiator outer cover 14 and a radiator inner cover 15 respectively including dust strainers outside of the radiator 13 are arranged at a predetermined interval, a brush arm with a brush threaded to the dust strainers of the radiator outer cover 14 and the radiator inner cover 15 is arranged at the interval part so as to be reciprocated.SELECTED DRAWING: Figure 4 |
