No answer to your specific question, but having had a smaller tractor or two (JD 750, JD 855), I definitely agree a snowblower is 100% the way to go in deep or heavy snow.
We don't get the light powdery stuff as often as we do the heavy wet stuff, but sometimes we get 24 - 36 inches of it in a single storm, meaning the weight per linear foot of travel is just absolutely massive. A JD 2-series would be good around here for pushing a plow blade through 6" or 8" of that kind of snow, but not the bigger storms, and a JD 1-series might be more limited to plowing in 4" - 6" of heavy snow. They have the mite, through smart gearing, but not the weight and traction.
I found that my JD 855, which was very similar in weight and size to a modern 2025R, was great at pushing snow up to 6" or 8" with a bucket on the loader. But when we'd get a foot or more of heavy wet stuff, it was time to mount up the PTO snowblower, since it'd be faster than trying to push or shovel that kind of weight.
