According to a second aspect of the present invention, there is provided a combine aggregator storage control method, comprising a discharge auger and a drive device for rotating and elevating the discharge auger. When approaching,
It detects whether the manual operation lever is ON, starts the automatic storage operation when it is ON, subsequently detects whether the manual operation lever is ON, and switches to the manual storage operation if it is ON. And According to a third aspect of the present invention, there is provided a method for controlling the storage of a combine a discharge auger.
The automatic storing operation is characterized in that when the discharged auger turns and approaches the augerrest, it rises once, turns right above the augerrest, and then descends onto the augerrest.

According to the first aspect of the present invention, when the discharge auger comes near the auger rest, the discharge auger stops once. Therefore, even if the manual operation is resumed thereafter, the rotation speed of the discharge auger is slow and the operation amount is small. It does not go too far beyond the storage position. Thus, the discharged auger can be easily stored on the auger rest without having to start over. According to the second aspect of the present invention, when the discharge auger turns and approaches the auger rest, the operation shifts to the automatic storage without any special operation in the manual operation state, and no trouble is taken. Can store the discharge auger. Then, when the manual operation is turned on again after the automatic storage is started, the operation shifts to the manual operation. In this case, since the discharge auger is located near the auger rest, the discharge auger can be stored by a small operation, and an erroneous operation such as excessive movement is unlikely to occur. According to the third aspect of the invention, when the automatic storage is performed, the discharge auger is once raised near the auger rest, so that the discharge auger can be positioned directly above the auger rest without interfering with the auger rest. Therefore, there is no problem such as damage.
