In plan view, the left and right sides (in this case, the right side) of the cab 5 are a part of the feeder house 11 (in this case, the left half) and a part of the beater case 18a that houses the beater 18 (in this case). Is covered with the left half) from above. Accordingly, the right half of the feeder house 11 and the beater case 18a protrudes outward in the right direction from the cab 5 in plan view. The right side part (side column 41a part) of the steering column 41 is located in the part which overlaps the left half part of the feeder house 11 and the beater case 18a in the cab 5. In the embodiment, a stepped portion 5 a corresponding to the beater case 18 a is formed on the left and right side plates (in this case, the right side plate) of the cab 5. The left half part of beater case 18a is accommodated in the lower side of cab 5 via step part 5a.

  If comprised as mentioned above, since the one side part of the driver's cab 5 overlaps a part of the feeder house 11, the lower part of the driver's cab 5 is used effectively, and the feeder house 11 is made into the front part of the traveling body 1. It can be connected to (the front face of the threshing device 9), and the cab 5 and the feeder house 11 are brought close to the center of the left and right width of the traveling machine body 1 without making the position of the cab 5 relative to the traveling machine body 1 so high. Can be placed. For this reason, the threshing device 9 located at the rear of the feeder house can be arranged close to the center of the left and right width of the traveling machine body 1, improving the balance of the center of gravity of the entire combine (lowering the center of gravity), and improving the running stability. Improvements can be made.

  In particular, in the embodiment, since the left and right sides of the cab 5 are overlapped with a part of the beater 18 together with the feeder house 11, the threshing device 9 can be positioned immediately behind the cab 5. For this reason, the presence of the beater 18 can contribute to the downsizing of the length of the combine in the front-rear direction while ensuring the ability to inherit the culm from the reaping device 3 to the threshing device 9.
