複雑となりやすい。(Prior Art and Problems to be Solved by the Invention) Threshing husks threshed by a threshing device pass through a culm transfer device that is disposed above a dust extractor that sorts threshing material, and are then crushed by a culling cutter. There is a form of cutting, but in order to achieve a good cutting action, it is desirable to have a substantially horizontal posture when throwing the culm into the culm cutter. However, the culm transfer device moves diagonally backward so that the culm moves from the base of the culm to the tip side, and the clamping position of the culm also moves from the culm side to the tip side. Therefore, when throwing the culm into the culm cutter, there is a disadvantage that the stock side hangs down and the culm cannot be thrown in a substantially horizontal posture. Therefore, a member such as a guide rod for supporting the stock side is provided. However, in such a case, the configuration around the dust collector tends to be complicated.
