Abstract
A scraper has an apron, a bowl, a cutting edge, a vehicle attachment, and a pivoting mechanism such that the scraper has a flat position and an angled position. In the flat position the cutting edge is in position to cut into dirt and store the dirt in the bowl, while in the angled position the scraper is rotated such that dirt within the bowl can drop onto the ground in front of the scraper.
