I bought the Super Duty Heavy Hitch, cart, and single point ripper attachment foe picking underground rocks from my meadow. I had my doubts that it would work without at least some manual digging. The first boulder I rolled out was bigger that my Kubota B-7800 tractor bucket with no manual labor at all. It was like picking up a pebble. I was astonished, and went on to roll out seven more that day. An amazing tool, beautifully made and finished, and from right here in the USA!! My only regret is that I waited so long to buy it!
The only limits of this tool are your imagination..
