PROBLEM TO BE SOLVED: To efficiently perform the reaping work of lodging culms by smoothly raising divided culms while preventing the interference of a lug of a vertical grass divider with a mobile grass-dividing plate even if the mobile grass-dividing plate placed at the reaped side is turned to the right or left.SOLUTION: The reaped-side mobile grass-dividing plate 40A positioned in front of a maneuvering unit 5 of the combine harvester is attached in a manner to be freely turnable in right and left directions around a vertical shaft P relative to a reaped-side grass-dividing frame 33 supporting the mobile grass-dividing plate 40A, an operation tool 43 to turn the mobile grass-dividing plate 40A in right and left directions is placed to a reaping apparatus 6 at a position operable from the maneuvering unit 5, a vertical grass divider 45 furnished with a vertically turnable lug 44 is placed at the outer side of a reaped-side raising device 37A positioned at the front side of the maneuvering unit 5, and the mobile grass-dividing plate 40A has an opened part 47 to pass the lug 44 of the vertical grass-divider 45 from the lower side upward independent of the right and left turned position of the mobile grass-dividing plate 40A.COPYRIGHT: (C)2009,JPO&INPIT【課題】既刈り側に設けた可動分草板を左右に回動操作しても、縦分草装置のラグがこの可動分草板に干渉せず、分草された穀稈を円滑に引起すことができるものとして、倒伏穀稈の刈取作業を能率よく行う。【解決手段】操縦部(5)の前側に位置する既刈り側の可動分草板(40A)を、該可動分草板(40A)を支持する既刈り側の分草フレーム(33)に対して縦軸(P)中心に左右回動自在に取り付け、該可動分草板(40A)を左右に回動操作する操作具(43)を操縦部(5)から操作可能な刈取装置(6)の部位に設け、操縦部(5)の前側に位置する既刈り側の引起装置(37A)の外側部に縦回し式のラグ(44)を備えた縦分草装置(45)を設け、可動分草板(40A)に、該可動分草板(40A)の左右回動位置に拘わらず縦分草装置(45)のラグ(44)が下側から上側へ向けて通過可能な開放部(47)を形成する。【選択図】図3
