I once watched a case 580 Backhoe literally wade into a marsh, floorboards awash, using his bucket and hoe to walk in.
He was installing a hydro pole so he would drag the pole, crawl walk the hoe and repeat `til he got to where he wanted to be.
He also dragged a 2 yard sled of crushed stone to bed the pole.
Once pole was installed he crawled walked back bringing the empty sled as well as the damaged pole.
The whole thing was simply awesome to watch. He walked that hoe about 150 yards over partially buried 3 and 4 ft boulders. Quite a show.
