Next, control for automatically avoiding an obstacle by the rotary divider 2a will be described. First, the controller 28 detects the obstacle sensor 5 when the harvesting and threshing operation of the combine proceeds and the rotary divider 2a moves forward along the bank.
Can move forward while detecting the shore (obstacle), and the detection information is always input. And control
When the obstacle sensor 5 detects a shore (obstacle) and approaches a distance requiring evacuation, the controller 28 outputs a control signal to the electric motor 3 and drives the motor to the evacuation side. It can be rotated so as to retreat to the side away from it, and safety can be achieved. In this way, since the position of the divider 2a is adjusted by the automatic control based on the detection information of the obstacle sensor, the operator is freed from the conventional troublesome manual operation and can concentrate on other operations of the combine operation. it can. Moreover, the obstacle sensor 5 can reliably detect the position of the ridge and control the evacuation and the like, so that the divider 2a
There is a feature that damage can be prevented beforehand, and work can be performed safely.

Next, the controller 28 sets the upper limit switch 30 in the process of continuing the control for avoiding the shore as described above.
If the upper limit position of the rotary divider 2a is detected and the information is input, the rotary divider 2a cannot be retreated any more. Therefore, the direction control of the combine vehicle body 6 is continuously switched to the side where the rotary divider 2a is separated from the ridge. Control.

Therefore, when the retracting operation of the rotary divider 2a reaches the upper limit and cannot move any more, the controller 28 controls the direction of the combine vehicle body 6 and changes the course of the entire combine to the side away from the ridge.
