The transmission of the engine noise to the outside of the column (24) is suppressed to a small level to further reduce the noise.

Further, a partition (27) for isolating the suction air passage (32) and the engine enclosed room (65).
In (a), a communication hole (69) communicating the air path (32) and the room (65) is opened, and the insertion hole (67) is also used as a ventilation hole for taking in outside air, and is provided at a low position. The air taken into the room (65) from the hole (67) flows out to the air passage (32) from the communication hole (69) above the opposite side to lower the ambient temperature in the room (65). The engine performance is maintained stably, and the cooling effect is promoted by the combination of the warm air flowing out from the communication hole (69) and the cool air from the suction port (28) in the air passage (32). ing.

In this embodiment, the radiator (2) having the above-described structure and requiring a large cooling air opening is used.
By disposing 2) away from the position where the engine (21) is arranged, it is possible to make the engine enclosed room (65) accommodating the engine (21) to be the most enclosed and to reduce engine noise. A sirocco fan (26) is provided for the radiator cooling fan for blowing and cooling the radiator (22).
By using this, static noise can be further reduced and noise can be further reduced as compared with a conventional radial fan.

Further, by providing the radiator (22) on the front side of the fuselage, maintenance and the like can be easily performed without removing the seat column or the like each time. By avoiding the vicinity of the fan (26) with a high incidence rate,
By sucking the outside air from the right side of the machine body which is not affected by the cutting operation etc. taken in from the outside air suction port (28) of the column (27), dust and straw chips etc. are introduced into the fan (26) and the radiator (22). Good work without clogging can be performed.

It is desirable to use a centrifugal fan such as a sirocco fan (26) or a cross flow fan as the radiator cooling fan, but an axial fan may be used.
