Not real sure what the area is that you want cleared or what your intended use will be. How dense is the growth?
Those 3 questions seem to me to be necessary to determine what you will want to do.
I had about 3/4 acre behind a house I wanted to thin out the < 10” trees and underbrush. I don’t plan to till it or build anything on it. I just wanted to reclaim it to walk through easily, keep it cut back easily and be able to fence it in.
There are some large trees, (oak, pine, sweet gum) from >10” - 36” out there that I’ll leave for now until I get the rest under control and decide what I want to do with it. Lawn, shaded recreation area, ???
Started taking out the < 10” pine and sweetgum trees and leaving ~36” high stumps so they were obvious and I wouldn’t run over them. Possibly that would be enough for some leverage to push/pull them out with the JD 110 backhoe. It really wasn’t.
Even stumps that small left pretty large size holes to fill in. I had a guy with a JD 333G and drum mulcher go over it and mulch the entire area including grinding down the ~36” stumps and some lower that I had cut lower up near the edge of the lawn. I paid for 4 hours @$150 so $600 and the stumps are gone and all underbrush is gone. Some areas were so overgrown you couldn’t walk through before he started.
I think it’s knocked down enough I can keep it under control and can take out a few more trees selectively. The area is fairly level but is not totally flat.
If I was going to plant a garden over the entire area, or build on it I would have needed to do something differently. I may decide to do that, later.
In the future, if I decide to take out some of the bigger trees I could push or fell them toward the rear of the property without concern that they would fall on any buildings.
