<P>PROBLEM TO BE SOLVED: To provide a reaping device which improves a reaping performance upon overall reaping, and which improves falling adaptive capacity by expanding a working area of a raising lag, while decreasing the production cost of a combine harvester. <P>SOLUTION: The reaping device is composed of a plurality of raising cases (12) on which a driving sprocket (14) is pivotally supported in a higher position, and a driven wheel body (18) is pivotally supported in a lower position, and a lag chain (16) provided with the raising lag (17) which is rolled on the driving sprocket (14) and the driven wheel body (18). The diameter of the driven wheel body (18) of either one of the raising cases (12) is larger than the diameter of the driven wheel bodies (18) of the other raising cases (12). <P>COPYRIGHT: (C)2012,JPO&INPIT |
