[0002]
[Prior art]
2. Description of the Related Art Conventionally, there has been known a combine that performs rolling control in which left and right crawlers are moved up and down relative to a vehicle body to maintain and control the left and right postures of the vehicle body in a horizontal posture.
[0003]
[Problems to be solved by the invention]
Since the combine uses a crawler as a traveling device, the vehicle body is at a low level, the passage of hot air due to heat radiation of the engine is poor, and the combine is likely to stagnate. The rolling sensor provided in such a place is difficult to maintain accurate detection due to high temperature.
[0004]

【The invention's effect】
The rolling sensors 38 1 and 38 detect that the crawler frames 6 6 are moved up and down with respect to the vehicle body 18 by the expansion and contraction of the rolling cylinders 25 25 when the traveling ground tilts left and right. The vehicle body 18 can be maintained and controlled in a horizontal state by the step between the crawler frames 6 and 6 . Since the rolling sensors 38 and 38 are provided in the vicinity of the outside air inlet 60 facing the inside of the selection tongue 59 of the threshing device 46, the vehicle body 18 is interposed between the left and right crawlers 2 and 2 while the threshing device 46 is threshing. Since the hot air in the space surrounded by the ground and the traveling ground is sucked from the outside air intake port 60 and blown to the threshing sorting portion, the stagnation of hot air between the left and right crawlers 2 and 2 is reduced. Thus, heating of the rolling sensors 38 and 38 can be reduced, and accurate rolling detection and control can be performed.
[0006]
Further, the configuration can be simplified by bearing the upper rollers 16, 16 that support the upper sides of the rollers 2, 2 by using the rear arm shaft 20.
