Find someone in your area who has their NPTC CS32 ticket, they will know what to do! If you have never done this before, best to get someone who has, too many things can go badly wrong.
This should be dealt with first as a leaning tree...face cut, bore cut, then release from the back.
It will get hung up, so then you take it out like a hung up, sever the hinge, leaving 25% on the side it might roll towards to act as a pivot. If the weight is right it will roll out on its own, if not, then either winch it out or roll it out using a turning strap to get it on the ground.
BE CAREFUL cutting the hinge, Stay OUT of the 'triangle of death' if you winch using a redirect, and STAY CLEAR of the butt, give yourself plenty of room, always be thinking, 'what will happen if this goes wrong?'
