Oh it's been stuck plenty of times! lol it's no man's land out there, believe me. My grandfather actually ran it off a levy once by accident and those big ole tires actually made it float.
He built another one that's probably 3 times bigger than that one. I don't have any pictures of it, but it was gnarly looking!
Here in Texas we kill all sorts of birds, mottled ducks, teal, gadwall, mallards, wood ducks, canvasback, redheads, pintail etc. lots of snow and speckle belly geese too
