How does the DR® Power Grader compare to a box scraper?
Box scrapers usually have 4 or 6 non-hardened scarifying teeth spaced 12″ apart. As a result, they are best suited for loosening soil. They don’t do a good job penetrating extremely hard driveway surfaces (and their non-hardened teeth quickly wear out on these surfaces anyway). That’s because they rely solely on the weight of the box scraper to dig – and on hard surfaces that’s just not enough.
