PROBLEM TO BE SOLVED: To provide an operating system for an auger to unload grains from a combine harvester, capable of smoothly making an engagement retention of the auger on a holding member for its housing by a manual operation.SOLUTION: The system works as follows. When a control means H actuates a turning actuator M2 by the turning operation instruction of a relevant instruction means D in making a manual operation treatment, based on the detection information from a turning position detective means Ry to detect a turning position of the auger relative to the machine body, the auger is determined to be turned from a position lying apart from a turning position for its housing to a turning position for its housing In response to the determination, the turning actuator M2s operation is put under control so as to forcibly halt the turning the auger.COPYRIGHT: (C)2010,JPO&INPIT【課題】手動操作により穀粒排出用オーガを格納用保持部具に係合保持させることを良好に行うことが可能なコンバインの穀粒排出用オーガの操作装置を提供する。【解決手段】制御手段Hが、手動操作処理において指令手段Dの旋回操作指令により旋回アクチュエータM2を作動させるときに、穀粒排出用オーガの機体に対する旋回位置を検出する旋回位置検出手段Ryの検出情報に基づいて、穀粒排出用オーガが格納用旋回位置から離れる位置から格納用旋回位置に旋回されたことを判別すると、その穀粒排出用オーガの旋回を強制停止させるように旋回アクチュエータM2の作動を制御する。【選択図】図5
