The tree almost outweighs your tractor, let alone the soil that needs to accompany the root ball. All in all, I am guessing you're talking about picking up three tons with a 2 ton tractor.
Just to give you an idea, I have a John Deere 4410 -- about the same weight and capacity as your PT. I just dug up some Eastern cedars in the 15 foot range. I dug around the roots with the backhoe, but I was digging to extract the stump, not to transplant the tree. Cutting the trunk off the root, my tractor stuggles to get the root ball out of the hole. There's one or two that I don't think I can get out safely (or even unsafely).
You are going to try and move a survivable root ball (about twice or three times the size of my root ball), the trunk, and all branches intact. I believe you need four or five times more tractor than you have.
I had a tree spade guy tell me one time that they would not spade anything over about 5 inches.
EDIT: My Eastern cedars are not as tall, but larger diameter (12ish inches at the base). Even so, I think you're fighting an uphill battle.
