A rockhound collects rock using a "belt", much like a paddle type scraper and tosses them into a hopper. A harley is a power box rake, meaning it's like a box scraper, but it has a spinning drum with carbide teeth that pulverizes the dirt and brings rock to the surface and collects them in the box until the end of the pass.
