I shouldn't have even been where I was with the JD. I was just using it to stage bales in the fields. It's a hilly area and they often roll down into the woods and waterways, and I happened to find that one we overlooked last season. I wanted it out so I could roll it out and re-bale it. I went down in (didn't feel TOO squishy...) and stabbed the bale, backed out about 8 feet and the front started sinking and then the tires instantly dug for China. I dropped the bale to lose the extra weight, but no dice.
Normally I'm using a small telehandler and I can just push myself out if I sink.
