  In the above conventional configuration, the exhaust port is formed at a low position below the fuselage, and the high-temperature exhaust discharged from the exhaust port stays in a narrow space below the fuselage and heat is generated, so that the exhaust pipe May become hot. Moreover, since the exhaust port is at a low position, mud soil splashed up by the traveling device may enter the exhaust port or the waste straw waste may be scattered and accumulated during the harvesting operation. If this occurs repeatedly, there are disadvantages such as the exhaust port becoming clogged and exhaust being unable to be discharged satisfactorily, and the exhaust pipe likely to become hot.

  Therefore, it has been desired to improve the cooling performance of the exhaust pipe that guides the exhaust discharged from the engine.

The switching mechanism 57 can switch the grain tank 5 to the maintenance posture by operating the operating tool 61 from the outer side of the machine body to release the engaged state of the engaging member 64.

〔Exhaust pipe〕
Next, the exhaust pipe 66 through which the exhaust from the engine 7 flows will be described.
As shown in FIGS. 1 to 4, the engine 7 is provided in a state located below the operation unit 3. Exhaust gas (combustion exhaust gas) exhausted from the engine 7 is sent to a muffler 67 located above the engine 7. The exhaust gas passes through and is exhausted, and the exhaust gas flows through the exhaust pipe 66 and is exhausted outward from the exhaust port 68.

  The exhaust cylinder 67a of the muffler 67 to which the exhaust from the engine 7 is supplied is provided so as to exhaust the exhaust in an obliquely left upward posture on the rear side. The exhaust pipe 66 is provided in a state in which the exhaust port 68 for discharging the exhaust to the outside is higher than the supply port 69 to which exhaust from the engine 7 is supplied. It is provided in a state extending upwardly between the device 4 and the grain tank 5.

  The exhaust pipe 66 has a supply port 69 to which exhaust gas discharged from the muffler 67 is supplied to the front side of the machine body so as to surround the outer periphery of the exhaust cylinder 67a of the muffler 67 and radially between the exhaust cylinder 67a. It is formed in a state with a gap. The exhaust pipe 66 is smoothly curved so as to change its posture from the supply port 69 to the front side straight portion 70 extending linearly in the obliquely left upward direction on the rear side and to change the posture from the front side straight portion 70 toward the rear of the body. A curved portion 71 as a bent portion formed by bending in a state, and a rear-side straight portion 72 as a horizontal extending portion extending linearly from the curved portion 71 toward the rear of the machine body in a substantially horizontal posture.
