Saying you have been in a lot worse situations than that just from looking at a picture is pretty big words as well. I've had my tractor stuck before and it looked as if nothing was wrong, but it was setting at just the right angle with the weight shifted in such a way that it could not get free. And once you get high centered, I don't care if you have R-1's, tracks, steel cleets or whatever they won't do you a big of good if they aren't touching the ground.
There was a guy on another tractor board that ended up flipping his JD (can't remember # I think it was 4310) trying to get up a steep muddy bank that gave way. He eventually got a tow truck to help him get it out. It's better to be safe than sorry regardless of what has to pull you out.
