問題があつた。 If the handling depth adjustment device is automatically operated based on the culm length detection result, the handling depth can be maintained at the appropriate depth without any special operation. It was difficult to do so. In other words, conventionally, the next step of reaping work was started with the handling depth adjustment device maintained at the final handling depth adjustment value from the previous reaping operation, but the culm length at the start of reaping and the If the final culm length fluctuates greatly, the handling depth adjustment device will have to be operated over a large range at the beginning of cutting, and it will take an appropriate amount of time to operate the handling depth adjustment device over a large range. As a result, a state in which the handling depth temporarily deviates significantly from the desired one is brought about. Furthermore, between a state in which the treatment depth is deep and a state in which the treatment depth is shallow, the latter case, which causes untreated parts, has a particularly large disadvantage. For this reason, a method has been proposed in which the handling depth adjustment device is automatically operated to the deepest handling adjustment value in the handling depth adjustment range, but in this case, although the problem of unhandling can be solved, it causes a large handling condition. There is a risk that the threshing equipment will be overloaded, and there is a problem in that it will put an unnecessary load on the threshing equipment, increase the generation of straw waste inside the equipment, and have a negative impact on the handling performance itself.

Focusing on the fact that the shortest length of a grain culm in a small area of a field does not vary greatly in other parts of the field, which is approximately constant throughout one field, the handling depth correction device is operated to Since the handling depth adjustment device can be operated to the deepest handling value from the previous mowing operation, at the beginning of mowing,
It is possible to prevent shallow handling as much as possible while also preventing the handling depth adjustment device from operating over a large range. It became possible to perform good handling depth control.
