To provide a combine satisfying the demand that: exhaust of an engine is easily diffused in air satisfactorily without staying at a low position inside a machine body; and furthermore there is a low risk of falling of the exhaust of the engine on an operation unit.SOLUTION: The combine comprises: a grain storage part 5 which is positioned behind an operation unit; a threshing device 4 which is juxtaposed with the grain storage part 5 along a machine body width direction; an engine 6 positioned below the operation unit; and an exhaust pipe 41 through which the exhaust from the engine 6 flows. The exhaust pipe 41 is extended to the machine body rear part through an interval between the threshing device 4 and the grain storage part 5 while an outlet 43 for exhausting the exhaust is in a position higher than an inlet 44 supplied with the exhaust, and comprises a first exhaust pipe 45 and a second exhaust pipe 46 which has a diameter larger than that of the first exhaust pipe 45 and is connected to the rear end of first exhaust pipe 45, and a connection part 47 between the first exhaust pipe 45 and the second exhaust pipe 46 is positioned in the machine body rear side from the front/rear middle position CL of the exhaust pipe 41.SELECTED DRAWING: Figure 5
【課題】エンジンの排気が機体内側の低い位置に籠ることなく大気中に良好に放散し易いものでありながら、運転部にエンジンの排気が降りかかるおそれを少なくすることが望まれていた。【解決手段】運転部の後側に位置する穀粒貯留部5と機体横幅方向に沿って並んで脱穀装置4が位置し、運転部の下方に位置するエンジン6からの排気が通流する排気管41が、排気が供給される入口44よりも排気を排出する出口43の方が高い位置になる状態で、脱穀装置4と穀粒貯留部5との間を通って機体後部まで延ばされ、第1排気管45と、それよりも大径で且つ第1排気管45の後端に接続された第2排気管46とを備え、第1排気管45と第2排気管46との接続部47が排気管41の前後中央位置CLよりも機体後側に位置している。【選択図】図5
