PROBLEM TO BE SOLVED: To provide a grass dividing device capable of sufficiently carrying out a grass dividing guide toward the outside, even when grain culms are long.SOLUTION: In a combine harvester equipped with a reaping part (4) for feeding grain culms to a threshing part (3) while reaping planted standing grain culms, a first narrow guide (15) capable of switching between a grass dividing posture for guiding the planted standing grain culms in the side of an unreaped field toward the outside of a machine body and a housing posture for housing the same to the side of the machine body, and a second narrow guide (16) located above the first narrow guide (15) and guiding the ear tip sides of the planted standing grain culms outer than the first narrow guide (15) by pushing toward the outside are installed on a lateral part on the side of an unreaped field of the reaping part (4).COPYRIGHT: (C)2012,JPO&INPIT【課題】穀稈が長稈であっても、外側方への分草ガイドが充分に行える分草装置を提供する。【解決手段】植立穀稈を刈り取りながら脱穀部(3)に供給する刈取部(4)を備えたコンバインにおいて、刈取部(4)の未刈地側の横側部には、該未刈地側の植立穀稈を機体外側方に案内する分草作用姿勢と機体側に収納する収納姿勢とに切替可能な第1ナローガイド(15)と、この第1ナローガイド(15)の上方側に位置して該第1ナローガイド(15)よりも植立穀稈の穂先側を外側方に押出し案内する第2ナローガイド(16)を設ける。【選択図】 図4
