We have the same mud here and I can't get into the pasture with truck or tractor.
What we do is lay down a series of tarps, opened up feed bags, or what ever works to keep the bale clean, and hand roll the bale across the mud to the location.
If it is far, we stop and take the just rolled over tarp and spread it in front of the bale/tarp the bale is currently on, and move forward. Repeat until bale is in desired location.
When that doesn't work, I cut the strings and fork it off into a tub, cart, or whatever, and carry it that way.
