I need to level 50 square feet around my fire pit to put in a patio. One end is about 6" higher then the other. I think this is to much work to do buy hand as it is all hard packed Georgia clay soil. Which would work better renting a Skid-Steer (bobcat) or a mini Dingo? I have used the Dingo with the tiller attachment, but not for digging and scraping. Also, I would assume that I would need a bucket with no teeth on it to get a smooth surface. Will that still get the job done? Thanks, I am just getting started on landscaping my first house.
