On our trip to Cleveland, OH, USA A few weeks ago, while going in to a Cracker Barrel for lunch somewhere near Lexington, KY, I saw these guys in the large earth movers working away. The filled the hoppers, as this one is doing. They needed a cat to push to keep it going or the large scrapers tires would spin.  The front of the scraper bobs a little, making it fuzzy from the motion.

Once full of soil, they made another run, letting it out neatly.  All it was about was making a level place where it was not level before.

Boy, I was impressed with how it is done but not by the vast amounts of land cleared of everything natural but dirt...seen several places along the trip.  I hope we can leave some for the critters and us and nature.
