It all depends on how much, and how big. I wanted to clear about 12 acres. I brush hogged everything an inch or so and smaller. Then I tried pulling up the biggers ones, pushing them over, etc. I found that in our heavy clay my B2710 wouldn't pull up over push completely over a very big tree. Many times the trees would just break if they were dead.
Then I went to the chain saw, figuring to cut trees of at ground level. Had problems keeping the chains sharp, from getting them in the dirt. It was also back breaking labor.
I had dirt work to do - a road to build and a tank (pond) to dig. Since the guy had his dozer on the job (along with other equipment) he agreed to push over and pile up all the remaining trees (50 maybe) for $500. MUCH easier than trying to do it with your compact tractor.
The only problem is that I now have 3 brush piles. They won't burn because most of the piles are dirt from the tree roots. Also, there are corresponding holes all over the property where the roots used to be. Not a real big problem, as there seem to only be 10 or so that need attention.
I plan to use my new bucket forks to help me sift the brush out of those piles and burn it. I've already sifted and burned one of the piles - without the forks - and it was a 3 or 4 hour job and involved getting on and off the tractor repeatedly.
For small areas around the property the brush hog, brush cutter attachment on my Stihl trimmer, and the chain saw get the job done. And of course the FEL to haul it to the brush pile.
