2. Description of the Related Art Conventionally, a pretreatment unit is provided at a front portion of a traveling machine body having a pair of left and right crawler traveling devices so as to be able to move up and down, and a Glen tank and a threshing unit are provided on one side and the other side of the traveling machine body. In a combine harvester that is configured to run in the field by operating the field, a Karafu fan and a pressure fan are installed in the machine width direction at the lower side of the threshing section to form a sorting air duct, and the handling cylinder mounted on the handling room and the lower part In cooperation with a rocking sorter that swings back and forth at, while performing cutting and grain culm transfer work by the pretreatment unit,
The first item leaked from the rocking sorter is recovered to the Glen tank via the first gutter and the lifting cylinder, and the second one is re-selected by the rocking sorter via the second gutter and the reducing cylinder. It will be collected later in the Glen tank, and during such work traveling,
When the amount of paddy in the grain tank reaches a specified amount, an alarm prompting paddy discharge is issued by detection of a paddy detection sensor arranged in the grain tank.

However, since the above-mentioned paddy detection sensor is designed to detect a specified amount of paddy in a state in which the traveling machine body is held in a substantially horizontal posture, in a field condition such as a soft mud field, If the traveling machine continues to work while tilted in the left-right direction, the traveling machine will already be in an excessively inclined state when the paddy detection sensor detects that the amount of paddy in the Glen tank has reached the specified amount. There was a fear that it would not be able to turn or run.

In addition, as described above, when the traveling machine body is traveling in the state where it is inclined in the left-right direction of travel, the weight on the side of the grain tank increases successively even if the amount of paddy has not reached the specified amount. If the operator is not aware of this, it is easy to induce unstable running postures and deterioration of followability during turning, which is also a cause of unfavorable turning and roughening the field. It was the current situation.
