Your question is best answered in my opinion by explaining that while you can drive a 100 screws with a drill/driver, once you have used an impact driver, you will never do it again!
That's perfect Coy :laughing::thumbsup:
Can I use that one?
Think of a land plane as a long "box" blade. It's the length of the skids "footprint" that add's the magic, it basically cut's a material reservoir at each blade and deposits them where the long skids tell them to as it travels over your road. The long skid will basically average out the grade below it. Think road grader and it's looong wheel base with the blade hanging in the middle, the longer the wheel base the less reaction the cutting edge will have to road irregularities. A rear *blade or box blade are basically reacting to the tiny sliver of ground that it's riding on and usually any operator input is too much, too late.
You can crown a road with one in a similar manner as a box blade by altering the 3pt hitch arms or an adjustable skid shoe.
*a rear blade on an angle will have a decent "averaging" effect but none at "straight" or perpendicular to the travel.
