PROBLEM TO BE SOLVED: To allow a threshing feed chain to convey grain culms smoothly and to facilitate the supply of manually mowed grain culms to the threshing feed chain.SOLUTION: At a conveyance starting end part of a threshing feed chain (8) is provided a manually mowed grain culm limiting member (18) which switches between a limited state for limiting the supply of manually mowed grain culms to a threshing feed chain (8) when disposed in a position opposite the top of the conveyance starting end part of the threshing feed chain (8) and a limitation cancel position for allowing the supply of manually mowed grain culms to the threshing feed chain (8) when withdrawn from the conveyance starting end part of the threshing feed chain (8) to upward. Vertical clearances to form conveyance passages for grain culms transferred from a reaping device (3) side to the threshing feed chain (8) side are maintained between the conveyance starting end part of the threshing feed chain (8) in the limited state and the manually mowed grain culm limiting member (18). |
