This guy was felling for firewood, and using the tractor to push it the way they wanted it to go. Pushed too hard, and this happened. I’m curious what method they used to extract the tractor without tipping it over.
Bad things can happen fast when they 'Barber Chair'.
At that juncture....I'd probably just take my Pole Saw and continue the back-cut. Let gravity do the rest. Tree has barber chaired as much as it's going to. It's just got about three thousand pounds of tractor hanging off it now.
You know that was kinda 'trippy'. Change of underwear likely required.
