PROBLEM TO BE SOLVED: To smoothly carry out reaping and threshing operations by smoothing the take-over of grain culms from the side of a reaping device to an auxiliary feed chain 3 and a main feed chain 2, reducing the grain culms from falling down and further reducing the grain culms from being drawn into a threshing chamber during the threshing. SOLUTION: This combine harvester is obtained by installing the auxiliary feed chain 3 formed into a narrower width than that of the main feed chain 2 side by side at the starting end of the main feed chain 2 for rearwardly feeding threshed grain culms.
