Yeah, my last house I decided to trim all 3 "branches" at the same time on a big oak. Each branch was bigger then a telephone pole around. I did the 1st 2 fine, 3rd was the biggest & took the most work. That's the one that when it snapped off thetree moved
And after that I was done
I'm up a tree 15-20' & exhausted, had to sit for about 30 minutes
Then I climbed back down
It really opened the back yard up - the branches had swept down to within 6' of the ground
This house I have topped 5 silver maples that were growing like telephone poles
That is when I switched to the sawzall
Blade gets stuck, pull the lever, leave the old blade, then toss a new blade in & back cut the tree
I actually used my truck to pull the top off in the direction I wanted
