PROBLEM TO BE SOLVED: To provide a combine-harvester capable of improving assembly/disassembly workability or the like of a reaping device or a second reaping blade, while a second reaping blade support mechanism can be constructed in a non-bulky state.SOLUTION: A combine-harvester includes: a reaping device provided with a first reaping blade a thresher having a threshing cylinder a traveling machine body provided with an engine and a driver seat and a second reaping blade 133 for cutting culms left unreaped by the first reaping blade. The combine-harvester has the second reaping blade 133 mounted on the traveling machine body via a left side frame 134 and a right side frame. The combine-harvester has a structure including: a second reaping blade support mechanism for moving vertically the second reaping blade 133 in linkage with vertical movement of the reaping device and a changeover lever 219 for connecting/disconnecting linkage between vertical movement of the reaping device and vertical movement of the second reaping blade 133. The second reaping blade support mechanism is arranged on the side part separated from a maneuvering seat between side parts of a feeder house of the reaping device, and the changeover lever 219 is arranged on the side part nearer to the maneuvering seat.COPYRIGHT: (C)2014,JPO&INPIT【課題】第2刈刃支持機構を嵩低く構成できるものでありながら、刈取装置または第2刈刃の組立分解作業性などを向上できるようにしたコンバインを提供する。【解決手段】第1刈刃を設ける刈取装置と、扱胴を有する脱穀装置と、エンジン及び運転座席を設ける走行機体と、第1刈刃の残稈を切断する第2刈刃133を備え、左側フレーム134及び右側フレームを介して走行機体に第2刈刃133を装着するコンバインにおいて、刈取装置の昇降動に連動させて第2刈刃133を昇降動させる第2刈刃支持機構と、刈取装置の昇降動と第2刈刃133の昇降動の連動を継断操作する切換レバー219を備える構造であって、刈取装置のフィーダハウスの側部のうち、操縦座席から離れた側部に第2刈刃支持機構を配置し、操縦座席に近い側部に切換レバー219を配置した。【選択図】図17
