I think I have an idea, but wanted to see what you high production farm/tractor experts thought from your experience. We use farm tractors in Florida to dry out the dirt after it rains or to mix better soil with the existing. The DOT also allows us to disk in the grass since there really isn't in topsoil prior to placing fill. We own several Challenger 675's which I think are 275 hp. They have what looks to be a 15' or larger disk. How many acres can you do a day in sandy material, flat ground and no obstacles? I use 7-10 acres an hour for our estimate, but operations says no way yet our cost reports show about 12 ac/hr.
