I can barely remember my uncle being the grader operator and having a
large steel wheel at each side to raise or lower the blade which was
mounted on a turntable to adjust the angle to the direction of travel.
This turntable was mounted to trailing arms from the front of the
machine, allowing it to be raised or lowered. The blade could be
tilted and slid out to one side or other. The whole apparatus was
towed behind a truck or tractor.
Latter, these were replaced with self propelled, hydraulically
operated machines we see today.


Sure, after he broke the first one. ;-)
