PROBLEM TO BE SOLVED: To provide a combine-harvester that, when transferring from forced raking control to traveling ganged control, if possible, changes over to traveling ganged control after finishing threshing work of grain culms that are conveyed by a feed chain, and that can perform the forced raking control in a short time.SOLUTION: The combine-harvester is configured to perform: traveling ganged control for interlocking turning-on/off of the drive of a preprocessing part 3, a feed chain 21, and a thresher 6 with traveling/non-traveling and forced raking control for driving them even when stopping traveling. When it is detected that an operation tool 54 is changed over to an operation state while currently performing the traveling ganged control, the combine-harvester starts to perform the forced raking control, however, when it is detected that the operation tool 54 is changed over to a release state while currently performing the forced raking control, continues to perform the forced raking control, with the following defined as one of the conditions that, before the detection, threshing detection means 19 detects changeover from presence to absence of grain culms in the preprocessing part 3 side.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2019,JPO&INPIT【課題】強制掻込制御から走行連動制御への移行の際、可能であれば、フィードチェーンによる搬送中の穀稈に対する脱穀作業が完了した後に、走行連動制御への切換を行うとともに、強制掻込制御の短時間の実行も可能なコンバインを提供することを課題とする。【解決手段】走行の有無に前処理部3、フィードチェーン21及び脱穀装置6の駆動の入切を連動させる走行連動制御と、走行停止している場合でもこれらを駆動させる強制掻込制御とを実行可能なように構成され、走行連動制御の実行中に前記操作具54の操作状態への切換が検出されると、強制掻込制御の実行を開始し、強制掻込制御の実行中に操作具54の解除状態への切換が検出された場合、該検出よりも前に、穀稈検出手段19によって前記前処理部3側での穀稈の有から無への切換が検出されたことを条件の1つとして、強制掻込制御の実行を継続する。【選択図】図9
