Spring storms usually result in several blow downs but I had one stop at a 45 angle, hung in a neighboring tree, root ball half out of the ground.
It right over the main path the water, about 18-20 inches at the butt, and worried me enough to give it a month to see if it would take care of itself. It didn't, and the grandkids were coming for a visit. Notched the bottom, cut from the top, and the butt dropped straight down with a thump that shook the ground. A second or two later the rest of the tree came with another earth shaking thump. As soon as it unloaded, the stump snapped backwards - didn't even think of that in my planing.
Thought I had been careful but was reminded, again, of the power of a tree coming down. Thinking about later I realized the tree could have rolled off the hang up, or hit another tree on the way down and leveraged the butt back at me faster than I was moving.
It didn't, straight drop with all that weight, so I came away looking like I knew what I was doing though it was my first 'leaner' of that size. Wife chewed me out pretty good for not having her nearby to get help if something went wrong. - had to agree that was a good point.
Comes a time when it is worth paying someone with more experience, I had in the past but wanted to try this one myself. Nothing says you can't watch and help, and be better prepared to do it on your own the next time.
Staring to warm up out there, wonder how many trees will come down this winter and spring.
