I have seen a scraper blade used at tractor pulls. Here is a rough picture of what it looks like. I was thinking about building one for smoothing out the driveway. The blades are shown in red. The front blade knocks over the high spots and the back blades fill in the holes.
Another option I have is to put side skirts on my IH rear blade and turn it into a box blade. I don't want to modify the blade or drill any holes so it might be a tougher design.
