Does the operator have to re-adjust the level of the blade after
starting the cut, making the blade parallel to the rear axles?
Is there some kind of automatic level thingy to keep the blade at the
same angle, or is that up to the operator?


I've never run a road grader, but bulldozers do indeed have a small
pendulum that the operator can watch to level the surface.
