Abstract:
PROBLEM TO BE SOLVED: To minimize, with a simple structure, a tendency for mown grass and dust to be deposited in a high-temperature area within an engine bonnet arranged in the rear part of a machine body.SOLUTION: Within an engine bonnet 20, there are installed a diesel engine 3, a cooling fan 33 arranged in front thereof, and an emission gas purification device 35. Within the engine bonnet 20, there is provided a cooling air guiding path 4 for guiding part of cooling air from the cooling fan 33 toward a high-temperature area H1 where the temperature of heat radiation from the diesel engine 3 and the emission gas purification device 35 is high. The cooling air guiding path 4 is formed by an opposing gap between an air guide 40 for guiding the air sending direction of the cooling air from the cooling fan 33 and a bonnet interior member existing upstream, in the air sending direction of the cooling air, of a place where the high-temperature area H1 exists.SELECTED DRAWING: Figure 5
