I did end up getting the Tufline Land Rake. It is a very well built piece of equipment. The angle is adjusted by a threaded ratchet bar that can be moved to either side. This rig works so much better than my grader blade at levelling my stone/dirt driveway at the old farm. I made two passes over it the other day. That filled in all the ruts from the winter. You might have thought someone did the work with a hand rake. I also took it up in the woods to do over my access road on our 36 acre woodlot. Recently my wonderful neighbors were burning brush. They managed to light the woods on fire, including our land. The fire department used my road for access and rutted up my road a bit. This land rake smoothed it right out in two passes.
