PROBLEM TO BE SOLVED: To address such a problem that power transmission to a grass-dividing cutting device is performed from a steering part side via a reaping blade, thereby complicating a transmission mechanism and increasing the weight of a reaper.SOLUTION: A table 11 is divided into a rear table part 28 having an auger 8, and a front table part 30 having a grass divider 29. The front table part 30 can be exchangeable with any of a first unit 31 that is mounted on the rear table part 28 with a reaping blade 13, and a second unit 32 that has an extension bottom plate 9A having the reaping blade 13 at the front end. An upper part of a grass-dividing cutting device 35 for cutting and dividing reaped grain culm and unreaped grain culm of the second unit 32 is supported to a lateral plate 6 by a support frame 41. The combine harvester further includes a conversion mechanism 27 that converts specified-directional rotation from an engine into a reciprocating turning operation, and a cross-directional transmission shaft 26 that transmits the output of the conversion mechanism 27 to the grass-dividing cutting device 35 and the reaping blade 13, where the transmission shaft 26 is disposed between the lateral plate 6 and the support frame 41.COPYRIGHT: (C)2014,JPO&INPIT【課題】分草用切断装置への伝動が操縦部側から刈刃を介して動力を伝達する構成であるため、伝動機構が複雑化し、刈取装置の重量が増大するという課題がある。【解決手段】テーブル11は、オーガー8を有する後テーブル部28と分草体29を有する前テーブル部30とに分割する。前テーブル部30は、刈刃13を取付けた後テーブル部28に取付ける第1ユニット31と、刈刃13を前端部に取付けた延長底板9Aを有する第2ユニット32とに交換可能にする。第2ユニット32の刈取穀稈と未刈り穀稈を切断分草する分草用切断装置35の上部を支持フレーム41によって側板6に支持し、エンジンからの一定方向回転を往復回動運動に変換させる変換機構27を設け、該変換機構27の出力を前記分草用切断装置35および刈刃13へ伝動する前後方向の伝動軸26を設け、該伝動軸26を、前記側板6と前記支持フレーム41との間に配置したコンバイン。【選択図】図7
