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.COPYRIGHT: (C)2016,JPO&INPIT【課題】手扱ぎ作業の能率を高めると共に、刈取作業時にはフィードチェンへの手扱ぎ穀稈の供給を規制して補助作業者の安全性を高める。【解決手段】手扱ぎ規制部材(42)の前部を刈取装置(4)の後部に設けられた支持部(38A)に上下回動可能に支持し、穀稈の搬送方向で手扱ぎ規制部材(42)の後端部が挟扼杆(12C)の前端部よりも後側に位置してフィードチェン(12B)への手扱ぎ穀稈の供給が規制される規制状態と、穀稈の搬送方向で手扱ぎ規制部材(42)の後端部と挟扼杆(12C)の前端部との間隔が拡大してフィードチェン(12B)への手扱ぎ穀稈の供給が許容される非規制状態とに切り換え可能な構成とする。また、刈取装置(4)の後部からフィードチェン(12B)の上側に向けて後方へ延伸し、フィードチェン(12B)との間で穀稈を挟扼する補助挟扼杆(40)を設ける。【選択図】図18
