This is a really old thread I'm reviving but I sure am glad I found it. I've been pulling down some trees in an area along an old creek bed where I'm building a pond. I've been doing it the hard way. First I use a subsoiler to bust as many spread roots as possible. Then I use a ladder to put a cinch chain around the tree about 8 feet above the ground, then run 40 feet of grade 70 chain to the draw bar of the tractor to pull the tree over. I am using an old tire for a damper about half way in the length of chain in case of chain failure (run the chain through the eye of the tire and let the tire hang on the chain). It has been so-so in the success rate. Of course, smaller trees with a trunk of 4 inches or less have been pretty easy since my land is sandy. However, some of the "trash" trees really surprised me. Chinese Tallow trees have pretty large spread roots as well as a major tap root. I'm going to build an A frame about 6 feet tall. I plan on making a complete triangle out of the pipe since portability isn't a necessity. The base pipe will be around 5 feet so I can haul it on my trailer. The base pipe will lay on the ground with the 2 upright pipes welded to it. That way I should get a pretty good footing but the frame will still be able to rock over as the tree comes up.
