while back I found a tow behind grader. Was perfect thing for leveling a driveway. It was a commercial built unit but appeared to be nothing more than a old boat trailer with an adjustable scraper blade in the middle. The tires were in the very back and had adjustable height. From the way I understand why a grader is better at leveling than a 3pt scraper blade it the wheel distance. As your tractor rises and falls over hills so does the scraper blade. This tends to dig in first as the front tires go up and then the blade comes off the ground(or almost if in float position) as the back tires go over hill. With a grader the blade stays level as the tractor clears the hill early and the grader back tire never get to the hill since the blade leveled it. Still looking for a picture and will update if I find one.
