I have popped a few trees but only chaired 1 bad. It was about a 40" Oak and it was leaning about 10 deg. into a field so most of the branches were toward the field also. There was a 6" deadman about 25 feet up in the tree on my standing side. Did about a 8" face cut then started cutting the back with my 272. I was planning to get a few logs out of the tree but the homeowner I was doing a favor for just wanted firewood. I was not planning to cut anything this big so I did not have my big saw. Needless to say when it started to go I chickened out because of the deadman and watched it chair about 10' in the air and stay there!!! That was fun to cut down and it solved the log problem also. CJ
