Does the operator have to re-adjust the level of the blade after

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.


I've been a township supervisor coming up on 20 years now. The crown
of a gravel road is critical. Too much and people won't drive on their
side of the road. Too little, water puddles or runs straight down the
road and not to the ditch.

All Graders have a crown gauge of some sort. Old ones were just a
pendulum attached to the blade. New ones have an electronic readout.
I've not seen anything automatic, the operator has to push the
cylinder. An auto unit would sure be nice, as one operator can't seem
to do the crown correctly.
