PROBLEM TO BE SOLVED: To solve such a problem that conventionally, an engine cooling air does not favorably pass to an opposite side of an engine, and consequently, engine cooling efficiency is low.SOLUTION: A feed chain 12B to be fed to a thresher 3 is configured to continuously change speed and transmit it by a hydraulic-type continuously variable transmission 10 for the feed chain. The hydraulic-type continuously variable transmission 10 for the feed chain is disposed in an exhaust-air exhausting air trunk of a cooling fan 100 for cooling an engine 62. A net 102 is provided on an opening provided at a prescribed part in front of a chain cover 101 that is provided at an outer lateral side of the feed chain 12B, and a part of the net 102 is located at a part of or at a lateral side of the whole of the hydraulic-type continuously variable transmission 10 for the feed chain.COPYRIGHT: (C)2015,JPO&INPIT【課題】従来、エンジンの反対側へのエンジン冷却風の通り抜けが良好でなく、エンジン冷却効率が低いという課題がある。【解決手段】脱穀装置3に供給するフィードチェン12Bはフィードチェン用油圧式無段変速装置10により無段階に変速して伝達する構成とし、フィードチェン用油圧式無段変速装置10は、エンジン62を冷却する冷却ファン100の排風排出風路内に配置する。フィードチェン12Bの外側方に設けたチェンカバー101の前方所定部分に設けた開口部にネット102を設け、該ネット102の一部は、フィードチェン用油圧式無段変速装置10の一部または全部の側方に位置させたコンバイン。【選択図】図3
