I cut this monster down with 026 with a 18" bar. I used my saw with a 20" bar to cut the lead and some big limbs off and when I went to crank it again gas had leaked all over the place and it would not crank so I was left with the small saw to take this big old tree down. Luckly a friend was able to pull it on over with his Jeep. The small saw lacked about 3" of cutting thru so I would say it was right at 39" in dia. The big saw cranked after we got this one on the ground so I guess it had flooded. I've never had a problem with it, but it is getting kind of old. The reason I left the stump so high is that there is barb wire in the bottom section which has stained it very dark. Ken, I will save you a pen blank from this little tree too.
