PROBLEM TO BE SOLVED: To provide a combine harvester which has a reaping portion capable of being synchronously driven with the speed of the vehicle, and in which the reaping portion can be driven without relating to the speed of the vehicle at the optional timing of a worker, when the vehicle body is stopped or backward moved.SOLUTION: The combine harvester in which the reaping portion is connected to the front portion of the self-propelled vehicle body having a travel portion, and the reaping portion is interlocked to the travel portion of the vehicle body to synchronize the reaping speed of the reaping portion with the travel speed of the travel portion is characterized by disposing a forcibly reaping portion-driving means for forcibly driving the reaping portion, even when the travel portion is travel-stopped or backward moved. Therefore, a raking reel can be rotated without relating to the speed of the vehicle, when the travel portion is travel-stopped or backward moved, and even when the travel vehicle body is backward moved, grain culms can be taken into with the raking reel. Thereby, workability on the side of a levee can especially be improved.COPYRIGHT: (C)2013,JPO&INPIT【課題】車速に同調して駆動する刈取部を備えながらも、機体を停止又は後退させた場合には、作業者の任意のタイミングで車速とは無関係に刈取部を駆動させることのできるコンバインを提供する。【解決手段】走行部を有して自走可能となした機体本体の前方に刈取部を連結し、機体本体の走行部に刈取部を連動連結して、刈取部の刈取速度と走行部の走行速度を同調させたコンバインにおいて、走行部を走行停止又は後退させた場合にも、刈取部を強制的に駆動させる刈取部強制駆動手段を設けているので、走行部を走行停止又は後退させた場合に車速とは関係無く掻き込みリールを回転させることができ、走行車体を後退させるときでも掻き込みリールにより穀稈を取り込むことができる。これにより、特に畦際での作業性を向上させることができる。【選択図】図1
