I dont have pictures but the dozer on my project to a dip to. The operator got to far down on the bank sideways and it slid all the way down into the bottom of the pond with a couple foot of water in it. Luckily the track hoe was still there and was able to grab the top of the dozer blade with the bucket and pull him back up out of it easily.

One thing I learned on my project is that tracked skidsteers and dozers arent that hard to stick. But track hoes and back hoes can go thru an amazing amount of mud and muck by pulling and pushing themselves along with there arm.
