I thought his purpose was to eliminate the humps in the middle of his driveway
caused by his vehicles going over a wet clay base before it dried out like concrete?
My driveway is .25 mile long with many layers of limestone of different sizes over 20 years added to the clay soil. It still gets humps as he described in the winter and spring and it too dries out like concrete in the summer. I adjust my rear blade at an angle and while it, and the tractor, are on level ground I drop the lift and draft levers all the way down then bring the draft back up just enough to hold the blade edge at ground level. A couple trips down and back gets rid of the hump and fills in the tire grooves. Then as it dries out more a couple passes with my landscsape rake brings the limestone up and evens it out. Looks like a new load after a rain washes off the clay from the stone.
It's not a perfect solution, I guess, and it takes some learning of the controls, but I have 20 years worth of that.
Most folks try to dig too deep with one pass and make a worse mess than before they started. The length of the top link is important too so the blade will dig in but not too aggressivly.
All this wouldn't matter in your Florida sand where the leveling is easy
