るコンバインの微調整操向装置。 By operating the fine adjustment steering lever 1 left and right, the electromagnetic steering valve ASV for automatic steering is switched, and pressure oil is sent to one of the left and right hydraulic steering brake devices to perform fine adjustment steering. In this configuration, the braking force of the hydraulic steering brake device is gradually increased depending on the operating time of the fine adjustment steering lever 1 by a braking pressure adjustment valve provided in the oil supply circuit to the hydraulic steering brake device. A fine adjustment steering device for a combine harvester, characterized in that the combine harvester is configured to ascend.
