I always chuckle when I see a post like this, and you see it often on snow removal forums. CDN Farm Boy is correct, you don't need the cab. I have yet to see anyone with a cab say, "I hate this cab, especially in the winter." I feel like replying, "You don't NEED an indoor toilet, you could just go out in the woods and dig a hole to do your business. Think of the money you save on plumbing, heating and floor space. However an indoor toilet is nice."
Regarding the cab... If I had to go out in an open station tractor in the dark, in a blizzard all bundled up with my ski mask, snowmobile suit, heavy duty gloves and -100 Cabela boots on, it would be a task I would dread. Instead I can't wait to put my light sweatshirt, pajama bottoms, no gloves and light boots, get in my warmed up tractor and get out in that blizzard at night and throw the snow around. The nastier the blizzard, the more fun it is to be in the cab. What would be an unpleasant task in an open station tractor, is a blast in a cabbed, heated tractor.
