Everybody please be careful whether you use safety equipment or not. I cut a locust tree that was only about 14-16 inches across at the base and maybe 30 feet tall. It got caught in the top of another tree and hopped of the stump but stayed standing. I hooked my long bull rope to the bottom of the tree maybe 3 feet up and pulled with my truck to pull the bottom out and get the tree down. When I stated to pull the butt stated to move then dropped in a whole about a foot deep and the tree stood straight up and fell 90 degrees to the right and landed on my buddies horse trailer. It all happened within about 30 seconds. Things can and will happen fast when cutting wood so don't take anything for granted, and be carefull.
