The grain harvested by the harvesting operation is traveled while being stored in a grain tank provided on the machine body, and when the grain in the grain tank reaches a predetermined amount, the travel is stopped, and the discharge auger is appropriately stopped. Is turned to discharge the grains to the carrier or the like of the transport vehicle.

[0003] The discharge auger is configured to have a length corresponding to the front-rear length of the fuselage, and to be capable of turning and lifting and lowering with respect to the fuselage. In order to prevent damage to the discharge auger itself and to ensure the safety of the surroundings, the auger is stored in a storage position at the top of the machine. And
At the time of the grain discharging operation, the kernel is rotated to the discharging operation position to perform the kernel discharging operation, and when the kernel discharging operation is completed, the kernel is rotated to the storage position and stored.

[0004] Thus, in order to rotate and elevate the discharge auger, drive devices such as a motor and a hydraulic cylinder are provided, and these drive devices are provided near the cockpit. The drive operation is carried out by the manual turning operation lever provided. That is, the operator turns the manual turning operation lever.
By operating, the discharge auger can be turned or raised and lowered to an appropriate position.
