The technology is also known. However, in such a conventional technique, for example, when the second cutting blade is raised, the cutting position becomes the upper part and the cutting length to be abandoned in the field becomes long, but the bottom plate (trough) of the auger and the ground are increased. Since the intervals were constant and did not change, the cutting straw was pulled backwards and became a cause of pooling.

On the other hand, the cutting straw on the stock side passes through the space between the auger bottom plate 9 and the ground to the rear, and the ground is abandoned. Next, if the grain culm is long culm, the second
The cutting blade 4 extends the hydraulic cylinder 11 to rotate the post-cutting processing unit E around the fulcrum axis P to raise it. Then,
Since the height of the auger bottom plate 9 against the ground is increased in relation to the cutting height adjustment, the discharge to the rear becomes good even if the cutting straw becomes long.
