Hello. I am in the process of clearing my woodlot. The property has not been cared for in over twenty years. My question is what type of chain would you experts recommend. I have alot of dead elm and locust. Some is standing, some is laying in the dirt. Alot of the dead stuff seems to have petrified. I am using a 359 with a 20" bar and a 372xp with a 24" bar. Thank you.
