Got stuck to the axles in boggy mud just after the ground thawed this spring while trying to get close to some firewood logs with my forklift. Went in fine, lowered the forks and loaded them up with poplar logs. The instant I tried backing out with the load the front sank, and being stubborn trying to get out, the rear too. Finally dumped the poplar logs (about time - duh!) but it seemed too late. I had the wood chipper on the back instead of the backhoe, so no help there. Stuck in a wet spot in my yard, with 4wd and rear diff lock both engaged!
Then the surprise - used the forklift pointed straight down (nearly fully dumped) and lower the boom - they stabbed into the ground only so far, then I could lift the front of the tractor up, stomped the difflock, and back up out of the rear ruts a half foot at a time, while curling the forks up a bit. Lower the front, pull the forks out, reset them in a new spot, and go again. Nice.
