The utility model provides a harvester to the maintenance of radiator and air cooling formula cooling machine etc. Can carry out easily. Have: the cooling water of engine (26) is cooled off in radiator (30), cooling fan (31) dispose in organism inboard and cooling radiator (30) for radiator (30), dust -proof case (29) have case main part (62) of accomodating radiator (30) and ventilate and the state that prevents the dust to pass through covers the dustproof cover body outside the organism of radiator (30) in order to permit, condenser (41) to the state that is located between dustproof cover body and radiator (30) is accomodate in dust -proof case (29), and condenser (41) can swingingly be supported for dust -proof case (29).
