The gang is pretty merciless, today, so I'll just toss out that I did almost exactly the same thing the first year I had my tractor. Went into a wet area with nothing on the 3pt, scooped up a full bucket, lifted, started to go forward and then the front end dropped in to the miasma of muck and ooze, up and over the front axle. Was able to push myself out using the FEL (lucky that I remembered someone on here mentioned that). Made a huge mess. Took a quick look around to see if I could put all the muck back where it was, throw some straw over it and deny that it ever happened, if asked, when I spied The Plant Manager, her arms akimbo and giving me that steely eye stare. So now you are "experienced". welcome to the club!
