Sometimes a bulldozer is used to push another piece of earthmoving equipment known as a "scraper" The towed Fresno Scraper, invented in 1883 by James Porteous, was the first design to enable this to be done economically, removing the soil from the cut and depositing it elsewhere on shallow ground (fill). Bookmarked and recommended!
