Cut down a 4 ft diameter red cedar tree here at the farm, had a real strange feeling about where to cut it, so cut about 2' above the ground, went right through. About 6" below the cut was a rail road spike and grown into the fork was a 1 ton truck coil spring, standing straight up. That sprng would have torn a sawmill blade all to pieces. Picked up the trunk with the grapple and that trunk went into the burn pit, too much junk in it to try and save. Those old farm place trees can be real bad.
I have a tree farm, pines and hardwoods, bushytails steadily helping me plant trees. They plant some decent white oaks and pecans, just in the wrong place, hard to tain them to plant correctly.
