PROBLEM TO BE SOLVED: To provide a combine harvester facilitating switching of a work mode and securing a large working space above a feed chain.SOLUTION: The combine harvester includes a support part disposed at a terminal part of a conveyance device (34), where the support part vertically rotationally supports a base part of a manual threshing regulation plate (40) extending to a feed chain (12B). The manual threshing regulation plate can be switched between a regulation state where the manual threshing regulation plates (40) is rotationally turned downward to regulate the feed of manual threshing grain culm to the feed chain (12B), and a non-regulation state where the manual threshing regulation plate (40) is rotationally turned upward to allow the feed of the manual threshing grain culm to the feed chain (12B).COPYRIGHT: (C)2014,JPO&INPIT【課題】作業モードの切換えが容易に行なえ、フィードチェンの上方に大きな作業空間を確保したコンバインを提供する。【解決手段】搬送装置(34)の終端部に支持部を配置し、支持部に、フィードチェン(12B)へ向けて延設される手扱ぎ規制プレート(40)の基部を上下回動可能に支持し、手扱ぎ規制プレート(40)が下方向に回動しフィードチェン(12B)への手扱ぎ穀稈の供給が規制される規制状態と、手扱ぎ規制プレート(40)が上方向に回動しフィードチェン(12B)への手扱ぎ穀稈の供給が許容される非規制状態とに切り換え可能な構成とすることにより解決される。【選択図】図15
