The front tractor and rear tractor are switched by exclusive tractor change motor (pulse
motor).
Operating keys on the operating panel and receiving a command rotates the tractor change
motor, moving the tractor change lever back and forth through gears so that the change gear
moves transversely. If the change gear is shifted to right, the rotational force is transmitted
to the front tractor gear, driving the front tractor. If the change gear is shifted to left, the
rotational force is transmitted to the rear tractor gear A, driving the rear tractor.
