The exhaust portion 29a formed at the end portion) is connected by the first exhaust pipe 38 which extends diagonally upward toward the rear and is arranged closer to the left and right inside of the cabin 19 when viewed from the rear. In this way, the particulate matter in the exhaust gas introduced into the particulate matter removing device 36 from the introduction port 36a is supplemented and removed by the above-mentioned supplementary filter, and the upper surface side of the particulate matter removing device 36 is removed. Moreover, it is derived from the outlet 36b formed on the left and right outer sides (specifically, the portion to the right).

By the way, when the trapping filter is clogged and the function of capturing the particulate matter is deteriorated, the particulate matter removing device 36 discharges a high-temperature exhaust gas from the engine 29 and supplements the high-temperature exhaust gas with the high-temperature exhaust gas. It is possible to perform a filter regeneration process in which the deposits adhering to the filter are burned to regenerate the function of the supplementary filter. This process may be automatically performed by a microcomputer such as an ECU when clogging is recognized by detecting a pressure difference of a predetermined value or more downstream and upstream of the supplementary filter.

The nitrogen oxide purifying device 37 is a urea SCR (Selective Catalytic Reduction) which is a kind of exhaust gas purifying device for purifying the exhaust gas from the engine 29. Then, the nitrogen oxide purifying device 37 pays attention to the fact that ammonia reduces nitrogen oxides to become nitrogen gas and water, and injects urea stored in the urea tank into the exhaust gas to generate ammonia gas. , Nitrogen oxides are reduced and purified by this oxidation by ammonia gas.

It is connected by the second exhaust pipe 39 piped in the vicinity of the back surface side of the purification device 37. In this way, the nitrogen oxides in the exhaust gas introduced into the nitrogen oxide purification device 37 from the introduction port 37a are purified by the above-mentioned reduction treatment, and are on the upper surface side and the left and right outside of the nitrogen oxide purification device 37. It is derived from the outlet 37b formed in (specifically, the portion to the right).

A tail pipe (exhaust pipe) 41 extends upward and backward from the outlet 37b of the nitrogen oxide purifying device 37. At the extension side end of the tail pipe 41, an exhaust port 41a that discharges exhaust gas that has been cleaned by the nitrogen oxide purification device 37 to the outside and has been cleaned to the outside is provided rearward in the discharge direction. An opening is formed in a state of facing diagonally upward. The exhaust port 41a is arranged and formed directly above the grain tank 6 behind the cabin 4.

The exhaust pipe 39 is also arranged below the rear window 23 so as not to overlap the rear window 23 when viewed from the rear, and the particulate matter removing device 36, the first exhaust pipe 38, and the engine 29 are also nitrogen oxide purifying. Since the tail pipe 41 is arranged below the device 37 and is arranged on the left and right outside (right side) that does not overlap with the rear window 23 in the rear view, the exhaust passage is located below the rear window 23 in the rear view. A flow path avoiding the rear window 23 (non-wrapping in rear view) is formed from the engine 29 arranged in the above, and extends to a position above the upper surface of the grain tank 6.

Further, the tail pipe 41 is inclined rearward and left and right outside (right side) from the nitrogen oxide purifying device 37 side upward, and the extension side end portion thereof is left and right with respect to the inclined portion. The exhaust port 41a is formed by being bent inward and downward and facing diagonally upward and rearward. The exhaust port 41a is located on the left and right outer side (specifically, the right side) end side of the cabin 4 when viewed from the rear.
