However, the former is merely for switching the starting end of the holding rail to the handling posture, so that the operator is suitable for handling other devices of the combine. It takes a long time to make adjustments, and the work becomes inefficient, and if the adjustments are wrong, the handling operation cannot be performed satisfactorily. In addition, the latter one has nothing to do with the configuration of the handling device at all, only improving the sorting performance. The problem to be solved by the present invention is that the adjustment at the transition from the harvesting operation to the manual operation is made simple and reliable, and the adjustment function at the time of the transition to the manual operation and the automatic adjustment of the sorting ability are performed. When a function and a combine are provided in a combine, the structure of the two is organically associated with each other, so that the function can be favorably performed with a simpler structure.
