It's leaning in the wrong direction, towards a road. I started cutting it and my battery died. Then I started using my reciprocating saw and the blade broke.I used to help my dad cut trees down for a living. Is the tree leaning or is it straight up? If it's leaning the wrong direction, you have a problem. If you try and notch it it will just fall the way it's leaning. If it's straight up, climb up and tie a rope to a high point but sturdy point of the tree. Then have the person holding the other end start pulling as you slowly cut the back of the notch. Make sense?
