The subject of this invention is a harvesting reaping part provided in the front part of a traveling body, the driving part provided in the back of the harvesting part, the threshing apparatus and the collection recovery part which collect recovers the threshing apparatus and grain arranged in the left-right direction at the rear of the driving part, and the rear of a threshing apparatus The exhaust structure of the combine equipped with the discharge rice straw processing part installed in the inside and the exhaust pipe which discharges exhaust from the engine installed under the driving part, and it is difficult for the exhaust gas to move toward the operator of the driving part, It makes the mud difficult to deposit. The exhaust pipe XP is inclined upwardly passed between the threshing apparatus 4 and the collection recovery part 5 from the exhaust discharge pipe 67A of the engine 60, and the exhaust outlet 70C of the exhaust pipe XP discharges straw. It was set as the exhaust structure arrange positioned above the process part 8 (54). Moreover, the subject of this invention is a harvesting part provided in the front part of a traveling body, the driving part provided in the back of a harvesting part, the collection recovery part which collect recovers the threshing apparatus and the grain provided in the left-right direction at the rear of the driving part, and the driving part The combine structure provided with the exhaust pipe which exhausts exhaust from the engine installed below makes exhaust gas hard to move toward the operator of a driving part, and it is hard to accumulate straw debris and mud throughout the exhaust pipe. The exhaust pipe XP passes obliquely upward between the threshing apparatus 4 and the collection recovery part 5 from the exhaust part 67 of the engine 60, and is supported by the housing 4S which comprises the threshing apparatus 4. It was set as the exhaust structure. Moreover, the subject of this invention is making it easy
