PROBLEM TO BE SOLVED: To provide a combine harvester where a second support attached with a reaping part via a beam is supported by a first support rotatably and horizontally turnably, improved in the operability and visual recognizability of a locking mechanism functioning to hold the second support irrotatably in subjecting the reaping part to horizontal revolution. SOLUTION: The combine harvester has the following construction: One end of the first support 20 is attached to the horizontally turnable first support 20, while the other end is engaged with a bearing bracket 21, which is fixed via bolts onto a seat 45 in a detachable way. The first support 20 and the second support 19 are furnished with spline teeth 38 and 40 respectively. When the cylindrical locking mechanism 43 with spline grooves slides, the first support 20 comes switchable between a rotatable unlocked mode and an irrotatable locked mode.
