Many years back when I was still in earth moving I watched for weeks 6 scrapers peel away a hill and fill the low spots so quickly you couldn't blink. Something that made them very efficient was the ongoing use of a grader to keep the tracks smooth and the scrapers screaming at peak revs. In wet weather they would get stuck but manage to wriggle their way out of trouble and plough on. They really are something to wach especially when being driven by a real operator.

Ive had the misfortune of working on scrapers, mostly the twin engined CATs, I never understood how they could be absolutely rooted in such a short amount of operating time, then I witnessed them working....oh my god.
