</font><font color="blue" class="small">( I have been pulling the small stumps with my mini excavator. I have found one tree that has a tap root to China.I almost turned my machine over trying to pull out a 2" stump. I can pull a 4" oak like a tent stake. I think it is a Beech. Have you found this or is it another tree? )</font>
Beech trees have a wide but not deep root system. They're pretty easy to take out. They're a lot like a spruce.
Tap root to China... Sounds like an Elm. Good luck, they're a real bugger. I've seen big backhoes fight with them for hours, and they were only 8-10" diameter.
