Hi Eddie,
I also have a long driveway to maintain. My little B6000 has a front end loader as well as a rear blade. Neither of these seemed to help much. The blades would just scrape along the surface. Just wouldn't bite into the road. I found a solution though. My grader blade has an edge on top and bottom. I can either pull forward with one edge, or flip the blade and push backward with the other edge. My solution was to weld some 1/2 x 1 "teeth" to the top edge. Now I flip the blade and drag it behind with the teeth down. It scarifies the road, and I can then grade with the other edge. It works great.
