It is brush not trees. They are about 10ft tall and form a canopy up above. Once you get thru the first layer (where the sun hits and the limb grow low) you can stand up and walk around. Very few low limbs bigger than a pencil and most of them are dead. I have aleady gotten the outer layer. Now I back up to a clump, throw a chain around them a couple of times (so it kinda makes a noose). Tighten up the chain. Wack'um down and pull them off. If you just cut a few of them, the canopy is so dence they will not fall.
I will try to remember tomorow to take/post pictures on this forum.
