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 【課題】機体後部に配設されたエンジンボンネット内の高温領域で刈草や塵埃が堆積する傾向を、簡単な構造で極力低減する。【解決手段】ディーゼルエンジン３と、その前方に配置された冷却ファン３３と、排ガス浄化装置３５と、がエンジンボンネット２０内に備えられ、エンジンボンネット２０内に、ディーゼルエンジン３及び排ガス浄化装置３５からの放熱温度が高い高温領域Ｈ１に向けて、冷却ファン３３からの冷却風のうちの一部を案内する冷却風案内路４が設けられ、冷却風案内路４が、冷却ファン３３からの冷却風の送風方向を案内する導風ガイド４０と、高温領域Ｈ１が存在する箇所よりも冷却風の送風方向における上手側に存在するボンネット内部材と、の対向間隔によって形成されている。【選択図】図５
