I've cut some pretty big osage, 20-24" diameter, and dealt with them by myself. But not nearly the biggest I've seen. I've passed up all the truly big ones. Been eyeing up a family of osage trees for years, even had permission to cut them a few years back, but never did. They are feak... ing... huge. Some leaning over so far, like dominos in freeze-frame, that the cows in that pasture are able to scratch their backs on them. Only 50 yards from the road and a gate. I could back right up to them, and probably load them with the farmers backhoe. They're just so big. And with those giant trees, you never know what's inside. Could be hollow, rotten, split. They might not be any good. I like em better in the 10-16" range.
