PROBLEM TO BE SOLVED: To provide a combine capable of arbitrarily setting a drive speed of a feed chain to supply a suitable amount of grain culm to a thresher.SOLUTION: A combine includes the first hydraulic infinite variable-speed drive (66) for changing the rotation of an engine (62) in a stepless manner and transmitting the rotation to a harvester (4), and the second hydraulic infinite variable-speed drive (10) for changing the rotation of the engine (62) in a stepless manner and transmitting the rotation to a feed chain (12B). When a predetermined amount or more of grain culm is detected by a grain culm amount sensor (116, 117 and 118) for detecting an amount of grain culm transported by the harvester (4) or the feed chain (12B), the output rotation of the second hydraulic infinite variable-speed drive (10) is caused to be sped up automatically. |
