PROBLEM TO BE SOLVED: To provide a combine harvester, with which when a hydraulic mechanism for travel speed change or rotation is built in a transmission case, a hydraulic unit equipped with a control valve for operating supplying and discharging of a hydraulic oil, to and from the hydraulic mechanism is arranged properly, and the maintenance operation of the hydraulic unit is readily carried out.SOLUTION: The combine harvester is equipped with the transmission case 10, which has a built-in hydraulic mechanism for travel speed change or rotation on the front of a machine body. The combine harvester is equipped with an operation part 5, at one lateral outside of the transmission case 10 and a support frame 2, that is shaken and driven vertically and supports a reaping frame on the other lateral outside of the transmission case 10. The hydraulic unit 57, which is equipped with a the control valve for operating supply and discharge of a hydraulic oil to and from the hydraulic mechanism, is arranged on the lateral side part of the support frame 2 side of the transmission case 10.COPYRIGHT: (C)2009,JPO&INPIT【課題】 コンバインにおいて、走行変速用又は旋回用の油圧機構をミッションケースに内装した場合、油圧機構に作動油を給排操作する制御弁を備えた油圧ユニットを適切に配置して、油圧ユニットのメンテナンス作業が行い易くなるようにする。【解決手段】 走行変速用又は旋回用の油圧機構を内装するミッションケース10を機体の前部に備える。運転部5をミッションケース10の右又左の一方の横外側に備え、上下に揺動駆動自在で刈取部4を支持する支持フレーム2を、ミッションケース10の右又左の他方の横外側に備える。油圧機構に作動油を給排操作する制御弁を備えた油圧ユニット57を、ミッションケース10の支持フレーム2側の横側部に備える。【選択図】 図2
