Used my neighbors today on a 1/2 mile long road that was all potted out from the winter. Road is mostly crushed asphalt grindings. I was amazed at how well it worked in a very little time. Flattened that road and filled them holes with just the material that was there. This tool is tough and worked well. Used it on 9,000 lb. BobCat S740. Plane the road going forward and rake it or put a nice flat on it going backward. Very well designed.
Every single video advertising a land leveler shows a demo where it's being used on already flat soil. Sorry but if I need a land leveler, it's not because my land is already flat and I need it "flatter".
