SUMMARY OF THE INVENTION Therefore, according to the present invention, in a combine in which a grain tank is arranged at the rear of an engine portion, an engine room for installing the engine is arranged so as to bite into the grain tank side. The surface area of the engine room cover that covers the outermost part of the room is enlarged, and the intake of radiator cooling air provided in the cover is also enlarged, so that a large-capacity cooling fan is used to take in cooling air with a large air volume and slow wind speed. It is possible to reduce the amount of dust and straw debris adhering to the dust-proof net of the radiator and improve the cooling effect.

In addition, a cooling air intake passage is provided on the outside of the front of the grain tank to open the cooling air intake of the radiator in the upper part, and it is clean from the position above the grain tank where dust and straw waste are unlikely to be mixed. It enables the intake of various air, reduces the adhesion of dust and straw waste to the dust-proof net of the radiator, etc., and intends to further maintain stable engine performance.
