PROBLEM TO BE SOLVED: To reduce a speed of a feed chain automatically during manual threshing, and to facilitate supply of grain culms.SOLUTION: The combine includes: a feed chain (13) disposed at a side of a threshing chamber (81) including a threshing cylinder (2), and conveying and supplying grain culms to the threshing chamber (81); control means (70) executing a manual threshing mode reducing automatically a rotation speed of an engine (16); mode switch means (71) switching the manual threshing mode between an effective state and invalid state; and a restriction member (77) disposed at a conveyance start end of the feed chain (13), and restricting supply of manual threshing grain culms to the feed chain (13). Upon release of the restriction of the supply of manual threshing grain culms by the restriction member (77), the manual threshing mode automatically switches to the effective state, the rotation speed of the engine (16) is reduced, and the driving speed of the feed chain (13) is automatically reduced. |
