PROBLEM TO BE SOLVED: To provide a combine that has a compact and strong constitution to support a hydraulic infinite variable-speed drive for driving a cooling fan.SOLUTION: A combine has a constitution in which a hydraulic infinite variable-speed drive (91) for a cooling fan is arranged over an engine (E), and the power of the engine (E) is transferred to an input shaft of a hydraulic infinite variable-speed drive (90) for traveling via a front upwardly inclined traveling HST belt transmission (34), then transferred from the input shaft of the hydraulic infinite variable-speed drive (90) for traveling to an input shaft of the hydraulic infinite variable-speed drive (91) for the cooling fan via a back upwardly inclined cooling fan HST belt transmission (35), and then the power is transferred from an output shaft of the hydraulic infinite variable-speed drive (91) for the cooling fan to the cooling fan (12) via a cooling fan drive shaft (32) arranged over the engine (E) along the longitudinal direction.COPYRIGHT: (C)2014,JPO&INPIT【課題】コンバインにおいて冷却ファン駆動用の油圧式無段変速装置のコンパクトで強固な支持構成を提供する。【解決手段】エンジン(E)の上方に冷却ファン用油圧式無段変速装置(91)を配置し、エンジン(E)の動力を前上り傾斜状の走行HSTベルト伝動装置(34)を経由して走行用油圧無段変速装置(90)の入力軸に伝達し、走行用油圧無段変速装置(90)の入力軸から後上り傾斜状の冷却ファンHSTベルト伝動装置(35)を経由して冷却ファン用油圧式無段変速装置(91)の入力軸に伝達し、冷却ファン用油圧式無段変速装置(91)の出力軸からエンジン(E)の上方に左右方向に沿うように配置された冷却ファン伝動軸(32)を経由して冷却ファン(12)に動力を伝達する構成とする。【選択図】図6
