PROBLEM TO BE SOLVED: To increase efficiency of manual threshing work and safety of an assist worker by restricting supply of manual threshing grain culms to a feed chain during reaping work.SOLUTION: A front part of a manual threshing restriction member (42) extended from a rear part of a reaping device (4) toward a front part of a holding rod (12c) is supported at a support part (38A) disposed at a rear part of the reaping device (4) so as to rotate vertically, the manual threshing restriction member (42) being switched between: a restriction state in which the manual threshing restriction member (42) rotates in the rear and downward direction, a rear end part of the manual threshing restriction member (42) is located on a rear side with respect to a front end part of the holding rod (12c) in a conveyance direction of grain culms, and supply of manual threshing grain culms to a feed chain (12B) is restricted and a non-restriction state in which the manual threshing restriction member (42) rotates in the upward direction, space between the rear end part of the manual threshing restriction member (42) and the front end part of the holding rod (12c) in the conveyance direction of the grain culms is enlarged, and the supply of the manual threshing grain culms to the feed chain (12B) is permitted.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】刈取装置(4)の後部から挟扼杆(12C)の前部へ向けて延出される手扱ぎ規制部材(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、手扱ぎ規制部材(42)が後下方向に回動し、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、手扱ぎ規制部材(42)が上方向に回動し、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。【選択図】図17
