I've got a very tall straight black walnut tree that i'm planning on taking down after the first frost. the top is dead and fungi is growing out of it at about 60' up but below that there are branches with live leaves. Anyway I've been told if I get it milled properly I might be able to sell the wood for enough money to buy a new tractor. Could this be true? what is the best way to proceed. there is a very large maple not far from it that has the same problem with the top being dead. Neighbor said it could be from the drought we had three years ago.
