Some 657B scrapers off loading in fill area

They are giant planes of the earth. They flatten a large surface quickly. Then a blade man, or grader operator comes behind them and puts on the finishing touches.

I am trying to understand the mechanics of these? What holds the dirt in after you are done filling? Is it the same door that you see rotating out off the way to unload?

@dlama1080 Yes the door in the front is called the "apron" it holds the material in after loading. When you arrive at the fill site, you lift the apron door & push the material out the front with the "ejector"
