Took down a big unhealthy ash yesterday, and the 064 performed beautifully. This tree had two 32" trunks that joined into one monster trunk about 5-6 feet above the ground. Thinking the tree could split apart as I cut, my buddy wanted to set up a platform and take the two trunks separately above the union, but I didn't like the idea of working on a platform. I settled for climbing up into the tree, ratchet strapping the two trunks together about 30' up, and taking the tree in one cut at the narrowest point below the trunk union. I took it with a 28" bar on the 064, and the tree stayed together until it hit the ground, upon which the two trunks separated. Photo is my spotter / landowner, not me.
