PROBLEM TO BE SOLVED: To provide a combine which is configured so that mechanical vibration of a forward-reverse rotation switching case 121 and a forward-reverse rotation operating device 132 is reduced and so that the connection structure between the forward-reverse rotation switching case 121 and the forward-reverse rotation operating device 132 is simplified.SOLUTION: The combine is provided with a harvesting device 3, a threshing device 9, and a moving machine body 1 which is provided with a moving section 2 and an engine 7, and the combine is configured so that stalks of grain are supplied from the harvesting device 3 to the threshing device 9. The combine is also provided with: the forward-reverse rotation switching case 121 which inputs the rotational driving force of the engine 7 into the harvesting device 3 and the forward-reverse rotation operating device 132. The forward-reverse rotation switching case 121 is disposed on one of left and right harvesting device supports 231 by which the harvesting device 3 is supported, and the forward-reverse rotation operating device 132 is disposed on the other of the left and right harvesting device supports 231.COPYRIGHT: (C)2013,JPO&INPIT【課題】正逆転切換ケース121と正逆転操作具132の機械振動を低減できると共に、正逆転切換ケース121と正逆転操作具132の連結構造を簡略化できるようにしたコンバインを提供しようとするものである。【解決手段】刈取装置3と、脱穀装置9と、走行部2及びエンジン7を設ける走行機体1を備え、刈取装置3から脱穀装置9に穀稈を供給するコンバインにおいて、エンジン7の回転駆動力を刈取装置3に入力する正逆転切換ケース121と、正逆転操作具132を備え、刈取装置3が支持される左右の刈取り支柱231の一方に正逆転切換ケース121を配置し、左右の刈取り支柱231の他方に正逆転操作具132を配置したものである。【選択図】図16
