PROBLEM TO BE SOLVED: To provide a combine harvester highly efficiently performing manual threshing work and having a feed chain with high transmission efficiency, the feed chain conveying manually-threshed grain culms.SOLUTION: The combine harvester comprises: a mode switch (6B) that performs a switching operation between a reaping/threshing mode for changing a conveying velocity (VF) of a feed chain (12B) synchronized with a conveying velocity (VH) of a reaping device (4), and a manual threshing mode for retaining the conveying velocity (VF) of the feed chain (12B) to a prescribed conveying velocity; and a speed control dial (6A) capable of changing the conveying velocity (VF) of the feed chain (12B). Only when the mode is switched to the manual threshing mode by the mode switch (6B), the speed control dial (6A) can change the conveying speed (VF) of the feed chain (12B). |
