Thanks. I think I'm going to cut those upper trunks off first. They are actually 3 trunks wrapped & twisted around each other and were growing as one trunk and then split into 2!
I just saw this in the photo, there's a little space near the roots. Maybe I can dig around there a little and get my saw blade in there & cut from the bottom?
Cut those upper trunks off and you just may find that "they" were causing the downward pressure on that lower leader. With the uppers out of the picture, you will probably be able to just cut from the top down near the root ball, if you haven't already.
