PROBLEM TO BE SOLVED: To provide a combine harvester designed so as to enable a reaping part to be readily mounted and demounted during maintenance operation of the reaping part before and after the operation and having a high operating efficiency by simplifying a hydraulic pipe without making the hydraulic pipe interfere with the vertically moving reaping part. SOLUTION: This combine harvester 12 is equipped with a traveling device 3, the reaping part 4, a driving operation part 7, a tank 9, a hydraulic infinite variable-speed drive 10, an oil forced feeding means for forcedly feeding an oil and a motor 11 which is a driving source for the reaping part 4, a threshing part 8, the hydraulic infinite variable-speed drive 10, etc. The combine harvester 12 is provided with a reaping vertical valve 14 communicating with a lifting and lowering means and the oil forced feeding means in one lateral part in the left and right directions of a traveling case 1 and comprising a relief valve 13 internally installed therein. A manifold 15 for making the other lateral part communicate with the hydraulic infinite variable-speed drive 10 and guiding the oil passing through the relief valve 13 from the side of the reaping vertical valve 14 to the side of the hydraulic infinite variable-speed drive 10 is integrally formed in the interior of the traveling case 1. |
