PROBLEM TO BE SOLVED: To remove dust on a dustproof net of a radiator cover and to remove an attachment on the dustproof net. SOLUTION: The combine harvester is constituted as follows. A wind-shielding plate 35 is installed in the inside of the dustproof net 30 so as to be freely reciprocally movable in the width direction of the radiator cover 20. The attaching force of the attachment attached to the dustproof net 30 by the sucking action of a cooling fan 13 is reduced by partially shielding the sucking wind of the cooling fan 13 by the movement of the wind-shielding plate 35. The attachment attached to the dustproof net 30 is moved together with the wind-shielding plate 35 while being attached to the dustproof net 30 at the vicinity of the edge terminal of the wind-shielding plate 35 because the sucking wind at the vicinity of the shielding has a flow velocity higher than that of the sucking wind at a part not shielded by the shielding plate 35. A dust-sucking opening 55 for sucking the attachment moved by the wind-shielding plate 35 is installed in a frame body 21 at the moving terminal end of the wind-shielding plate 35.
