PROBLEM TO BE SOLVED: To solve such the problem that, since a conventional second cutting blade has a configuration that both right and left sides of a cutting blade frame is supported by a pair of right and left support frames, the second cutting blade inclines when one of the longitudinal support frames comes into contact with an obstacle or the like.SOLUTION: In a combine, a support mechanism 21 of a second cutting blade 20 is configured so that a lateral cutting blade 23 attached with the second cutting blade 20 is attached to lower parts of a plurality of longitudinal support frames 22 directed in a longitudinal direction. One of the longitudinal support frames 22 is attached to the cutting blade 23 while the length thereof is fixed, and the rest of the longitudinal support frames 22 are attached to the cutting blade 23 so that the length thereof is variable.COPYRIGHT: (C)2015,JPO&INPIT【課題】従来の第二刈刃は、左右一対の支持フレームにより刈刃フレームの左右両側を支持する構成のため、一方の縦支持フレームが障害物等に接触すると、第二刈刃が傾斜するという課題がある。【解決手段】第二刈刃20の支持機構21は複数の縦方向の縦支持フレーム22の下部に第二刈刃20を取付けた横方向の刈刃フレーム23を取付けて構成する。複数の縦支持フレーム22のうちの一つは刈刃フレーム23に長さ固定状態に取付け、残りの縦支持フレーム22は長さ変更可能に刈刃フレーム23に取付けたコンバイン。【選択図】図2
