I am cutting down a Tree that is so dead it has turned into a dirt statue!

This is a video about me cutting down a tree that has turned into a dirt statue. I’m using a steel 500 I fuel injected chainsaw. This tree is a oak tree that is infested with bugs and they have the tree away and it has turned into Dustin so I am trying to cut this tree down and it has nothing but nails in it and wire and pipes and so my chainsaw wouldn’t cut it
