You better have extra chains for the saw, and they better be sharp...it is a extra hard, dense, heavy, wood.
As far as I know, Ironwood is the only thing harder.
This is why it makes such good fish cover....it will last a couple lifetimes.
I have never cut a full tree, I had 3 sources bring me truck loads of big limbs....it took me forever to try to hand saw them to size.
I broke out the chain saw and I dulled a chain. Then I started adding limbs to concrete, after they dried, I realized unlike other limbs these weighed alot more....some sets took 3 guys to drop....BUT IT WAS WORTH ALL THE WORK!
