PROBLEM TO BE SOLVED: To improve the grass dividing capability and to improve the working efficiency by attaching a rotary cutting blade for cutting crop culms before grass dividing at the distal end of a grass divider.SOLUTION: The universal combine harvester includes: a pair of right and left grass dividers (3R and 3L), a raking reel (5) for raking the culms introduced into an introduction pathway between the right and left grass dividers (3R and 3L) rearward； a hair-clipper type reaping device (6) for reaping the raked culms from the roots； and a pre-reaping part (9) having a raking auger (8) for raking the reaped culms rearward and conveying the culms in the lateral direction. In the universal combine harvester, the rotary cutting blade (12) for cutting the culms before grass dividing is disposed at the distal end of the grass divider (3L) located on the unreaped side of the right and left grass dividers (3R and 3L).【課題】分草具の先端に分草前の作物茎稈を切断処理する回転刈刃を設けることによって分草性能を高め、作業の能率化を図る。【解決手段】左右一対の分草具（３Ｌ，３Ｒ）と、該左右の分草具（３Ｌ，３Ｒ）の間の導入経路内に導入された茎稈を後方に掻き込む掻込リール（５）と、掻き込み後の茎稈を株元から刈り取るバリカン式の刈取装置（６）と、刈取後の茎稈を後方に掻き込んで横送りする掻込オーガ（８）を有する刈取前処理部（９）を備えた汎用コンバインにおいて、左右の分草具（３Ｌ，３Ｒ）のうちの未刈側に位置する分草具（３Ｌ）の先端部に、分草前の茎稈を切断する回転刈刃（１２）を設ける。【選択図】 図１
