Here's some more pictures of 2 WD tractor in snow, we have about a foot of snow in the woods, and I was fooling around trying to see what the limits were.
With just V-chains and no rear ballast it went pretty good in a straight line, no big fear of getting stuck, but not maneuverable, couldn't really steer, front tires would just plow forward, even skid steering was not effective. I do have 4 suitcase weights on the front to counter the rear plow I usually have on the back, so that probably makes the poor steering worse.
Then I tried it with my JD concrete filled ballast box, which is quite heavy, with out the weight on front it would stand right up I'm sure.
It was truly unstoppable, the weight distribution was perfect, making the front end light enough to not dig in and plow but not to light to make it uncontrollable, and using the brakes for skid steering was incredible doing zero turns in a foot of snow or solid ice. Was easy to maneuver thru woods trails turning with ease with brakes. tried driving over a mound of frozen snow bank, it would have gone right over except the box got hung up in back from the extreme angle, got out of it easily though.
