[Prior Art] When one step of the reaping operation is completed and leaves the field,
In order to prevent the front end of the mowing portion from hitting the ridge, it is a common practice to raise the mowing portion slightly before the mowing operation is completely interrupted or terminated. In such a case, if the handling depth adjusting means is operated only based on the information of the tip position detecting means, it is not possible to follow the change of the grain culm length (the length from the grain culm supporting point to the tip by the transport device). It tends to be shallow.

On the other hand, during the mowing work, the selecting means is set to the non-mowing state, and if there is unevenness in the field, the unevenness can be dealt with by raising and lowering the cutting unit. At this time, even if the mowing part is operated on the ascending side, the non-mowing state is selected and the mowing operation is not performed, so that the handling depth adjusting means does not operate on the deep handling side.
