I let two fellers live on my farm for free it's nice to have an extra hand to help with projects once in a while . One has a 8x12 the other an 8x8 insulated "house" there are a lot of minimalist out there.
I have never used a 3 point unit but I think a stand alone is better I have a 5.5 honda on mine an it splits 95% of what I give it ,why put hours on a big expensive tractor engine ,plus your tractor is free to transport logs.
