PROBLEM TO BE SOLVED: To improve efficiency of manual threshing work, and to improve safety of an assist worker by restricting feeding to a feed chain of grain culms to be subjected to manual threshing in reaping work.SOLUTION: The combine can be switched between: a restriction state in which a front part of a manual threshing restriction member 42 is supported on a support part 38A arranged in a rear part of a reaping device 4 so as to rotate vertically, a rear end of the manual threshing restriction member 42 is positioned at a rear side with respect to a front end of a holding rod 12C in a grain culm conveyance direction, and feeding to a feed chain 12B of grain culms to be subjected to manual threshing is restricted; and a non-restriction state in which a distance between the rear end of the manual threshing restriction member 42 and the front end of the holding rod 12C is enlarged in the grain culm conveyance direction and feeding to the feed chain 12B of grain culms to be subjected to manual threshing is allowed. An auxiliary holding rod 40, which is extended backward from the rear part of the reaping device 4 toward an upper side of the feed chain 12B and holds the grain culms between the auxiliary holding rod 40 and the feed chain 12B, is arranged. |
