I started this yesterday. There's part of an old foundation to take out then just smooth out the area to the adjacent land. I have about 2 hours in it so far. It was an old barn at one time and the foundation was just rocks and concrete for a base with concrete block building off of that. I think each block must be about 500 lbs or so. You can see a couple I placed on top of the hole. All I have is a skid steer but it seems to be doing OK. A mini ex would be faster but I still would need to grade it later so the extra for a mini ex wouldn't be worth the effort.
