PROBLEM TO BE SOLVED: To prevent unexpected traveling during reaping operation in a state that traveling is stopped at the side of a levee etc.SOLUTION: A combine harvester is obtained by installing a reaping part 4 capable of carrying out non-stage gear shift of operation number of revolutions with a hydrostatic type infinite variable-speed transmission 21 for reaping and transporting in front of a traveling device 3 capable of carrying out the non-stage gear shift of traveling speed with a hydrostatic type infinite variable-speed transmission 12 for traveling, and installing a thresher 2 above the traveling device 3. In the combine harvester, the reaping part 4 is composed so that the infinite variable-speed transmission 21 for reaping and transporting is subjected to gear shift and driving synchronously with the traveling speed subjected to the gear shift by tilting operation of a main gear shift lever 13 of the infinite variable-speed transmission 12 for traveling installed in an operation part 6 which is provided with a reaping and driving ON and OFF means 53 for driving the reaping part 4 in the state that the traveling of the traveling device 3 with the infinite variable-speed transmission 12 for traveling is stopped.COPYRIGHT: (C)2010,JPO&INPIT【課題】畦際等の走行停止態の刈取作業中の不意な走行。【解決手段】走行用静油圧式無段変速装置12により走行速度を無段階に変速可能な走行装置3の前方に、刈取搬送用静油圧式無段変速装置21により作業回転数を無段階に変速可能な刈取部4を設け、走行装置3の上方には脱穀装置2を設け、前記刈取部4は、操縦部6に設けた前記走行用無段変速装置12の主変速レバー13の傾倒操作により変速された走行速度に同調して刈取搬送用無段変速装置21が変速駆動する構成とし、前記操縦部6には、走行用無段変速装置12による走行装置3の走行を停止させた状態で、刈取部4を駆動させる刈取駆動入切手段53を設けたコンバイン。【選択図】図3
