PROBLEM TO BE SOLVED: To provide a combine harvester in which operation switches are arranged so as to prevent operational error of an operator, have good operability and improve efficiency of a series of agricultural operation.SOLUTION: An operation part 40 in which operation switches and dials (41-43 and 41a-43c) are installed is installed in front of a driving seat 20 and the operation switches and dials are formed in the shapes protruded from an installation surface and the operation switches and dials (41-43) having relatively large degree of projection are installed in the positions separate from the driving seat and operation switches and dials (41a-41c, 42a-42c and 43a-43c) having relatively small degree of projection are installed in the positions close to the driving seat. In the combine harvester, preferably, operation switches and dials (41-43) continuously controlling various kinds of functions of the combine harvester are preferably installed in positions separate from the driving seat and operation switches and dials (41a-41c, 42a-42c and 43a-43c) for carrying out on-off operations having various kinds of function are preferably installed in the positions close to the driving seat.COPYRIGHT: (C)2008,JPO&INPIT【課題】オペレータの誤操作を防止して、操作性が良く、一連の農作業の効率を向上させる操作スイッチ類の配置としたコンバインの提供である。【解決手段】操縦席20の前方に操作スイッチ、ダイヤル類(41~43、41a~43c)が設置された操作部40を設け、該操作スイッチ、ダイヤル類を設置面から突出した形状とし、比較的突出度合いの大きい操作スイッチ、ダイヤル類(41~43)を操縦席から離れた位置に設け、比較的突出度合いの小さい操作スイッチ、ダイヤル類(41a~41c、42a~42c、43a~43c)を操縦席から近い位置に設ける。また、コンバインの各種機能を連続的にコントロールする操作スイッチ、ダイヤル類(41~43)を操縦席から離れた位置に設け、各種機能の操作の入り切りを行う操作スイッチ、ダイヤル類(41a~41c、42a~42c、43a~43c)を操縦席から近い位置に設けても良い。【選択図】図4
