PROBLEM TO BE SOLVED: To provide a combine-harvester which is high in the performance of a manually threshing work and in the transmission efficiency of a feed chain.SOLUTION: A combine-harvester comprising a manual regulation member (38) capable of switching a regulated state for regulating the feed of a manually threshed grain culm to a feed chain (12B) and a regulation-released state for releasing the feed regulation of the manually threshed grain to the feed chain (12B). The combine-harvester further comprises: a control device (85) for controlling the speed of a stepless speed control device (10) automatically into a speed, at which the transfer speed (VF) of the feed chain (12B) is synchronized with the transfer speed (VH) of a threshing device (4), when the manual regulation member (38) is switched to the regulated state, and into a constant transfer speed (VF1) irrespective of the transfer speed (VH) of the threshing device (4), when the manual regulation member (38) is switched to the regulation-released state.COPYRIGHT: (C)2014,JPO&INPIT【課題】手扱ぎ作業の能率が高く、フィードチェンの伝動効率が高いコンバインを提供する。【解決手段】フィードチェン(12B)への手扱ぎ穀稈の供給を規制する規制状態と、フィードチェン(12B)への手扱ぎ穀稈の供給規制を解除する規制解除状態とに切替可能な手扱ぎ規制部材(38)を備え、手扱ぎ規制部材(38)が規制状態に切り替えられている場合に、フィードチェン(12B)の搬送速度(VF)が刈取装置(4)の搬送速度(VH)に同調した速度に自動的に変速され、手扱ぎ規制部材(38)が規制解除状態に切り替えられている場合には、フィードチェン(12B)の搬送速度(VF)が刈取装置(4)の搬送速度(VH)に拘らずに一定の搬送速度(VF1)に維持されるように、無段変速装置(10)を変速制御する制御装置(85)を設けることにより解決される。【選択図】図23
