I have to say on of the best dirt moving attachments is our old 3 point hitch box blade.They pull dirt forward & can shove backwards just as easy as pie.They also have the ripper shanks to loosen up hard pan soil.I love it.We use it after the dozer to take out track marks & pick up small debris .I added some adjustable gauge wheels to the blade this afternoon.I wanted it to perform more like a road grader .I robbed the wheels off of an old grain dryer that we no longer use.
