PROBLEM TO BE SOLVED: To provide a combine harvester made as not capable of operating a reaping clutch lever and threshing clutch lever to IN-positions when a sub-transmission lever is at a road-traveling position, etc., by a relatively simple structure.SOLUTION: At the middle part of an engaging plate 39 of the reaping clutch lever, a fixing plate 42 which has a bent tip end part at a machine body front side, is fixed by a bolt with the engaging plate 39, and e.g. when the sub-transmission lever 7f is at the position of road-traveling, and in the case that the rear end part of a swinging arm 37 hits the bent part at the front end of the fixing plate 42 (integrated with the engaging plate 39), since the plate 39 can not move in an arrow mark (A) direction, the reaping clutch can not become the IN-position. Also, in the case that the sub-transmission lever 7f is at a neutral position and the reaping clutch lever 28 becomes the IN-position, the rear end part of the swinging arm 37 is positioned at the lower side of the plate 39, and since the plate 42 blocks the rotation of the arm 37 in an arrow mark C direction, the sub-transmission lever 7f can not rotate to the road-traveling side.COPYRIGHT: (C)2011,JPO&INPIT【課題】比較的簡単な構造で副変速レバーが路上走行位置に有るときなどには刈取クラッチレバーと脱穀クラッチレバーが入位置へ操作できないようにしたコンバインの提供。【解決手段】刈取クラッチレバー連繋プレート39の中間部には機体前側の先端部が折れ曲がった固定プレート42が連繋プレート39にボルト止めされており、例えば副変速レバー7fが路上走行時の位置にあるときに、揺動アーム37の後端部と固定プレート42(連繋プレート39と一体)の前端部の折れ曲がり部が突き当たるとプレート39は矢印A方向に動けなくなるので、刈取クラッチが入になることがない。また、副変速レバー7fが中立位置にある場合に刈取クラッチレバー28が入となると、揺動アーム37の後端部はプレート39の下側に位置することになり、プレート42がアーム37の矢印C方向への回動を止めるので副変速レバー7fが路上走行側へ回動出来なくなる。【選択図】図4
