PROBLEM TO BE SOLVED: To provide a reaping part of a reaping harvester designed to sufficiently save energy in reaping and butt reaping and butt reaping operation of plant stand grain culms at the side of a levee and protect a grass divider, etc., when the grass divider contacts the levee or the ground surface by installing the grass divider for moving the tip in the front and rear directions without changing the position of the rear of the grass divider relatively to a grain culm raising-up body.SOLUTION: The reaping part of the reaping harvester is composed as follows. The grass divider 2 for dividing the plant stand grain culms and the grain culm raising-up body 11 for raising-up the divided grain culms are installed in a reaping part frame 9 and the raised-up grain culms are reaped with a reaping blade 13. The tip of the grass divider 2 supported with the reaping part frame 9 is freely movably installed in the front and rear directions while fixing the rear position of the grass divider relatively to the grain culm raising-up body 11.COPYRIGHT: (C)2007,JPO&INPIT【課題】穀稈引起体に対し、分草体後部の位置を変えることなく先端部を前後方向に移動させる分草体を設けることにより、畔際の植立穀稈を十分に刈取り枕刈り作業を省力化すると共に、分草体が畔や地面と接当した際に分草体等を保護することができる刈取収穫機の刈取部を提供する。【解決手段】 刈取部フレーム9に、植立穀稈を分草する分草体2と分草された穀稈を引き起す穀稈引起体11を設け、引き起された穀稈を刈刃13によって刈取る刈取収穫機の刈取部であって、前記刈取部フレーム9に支持される分草体2を、穀稈引起体11に対し分草体後部位置を固定したまま、先端部を前後方向に移動自在に設けた構成とする。【選択図】 図2
