PROBLEM TO BE SOLVED: To enhance efficiency in reaping work by making driving speed of a feed chain variable independently from a reaping transfer speed of a combine harvester with a simple constitution.SOLUTION: There are provided a first continuous transmission device (66) for continuously speed-changing rotation input from an engine (62), and outputting it to a travelling device (2) and a reaping device (4); a second continuous transmission device (10) for continuously speed-changing rotation input from the engine (62), and outputting it to a feed chain (12B); a speed sensor (34S) for detecting a speed of rotation transmitted from the first continuous transmission device (66) to the reaping device (4); and a control device (85) for speed-controlling the second continuous transmission device (10) on the basis of the speed of rotation detected by the speed sensor (34S). |
