If it's a 4wd tractor then I would strongly recommend the pull behind 3pt blower. Reason I say is with 4wd you should have ample traction to drive through the snow in most instances. The benefit of this is you are driving away from the snow ploom... not INTO the snow ploom. Trust me when I tell you spending a couple hours out in the cold now soaked cause the snow came down on you and then melted on your jacket, hat, gloves, face, legs etc.. sucks BIG. I know that all too well. Of course, going used will limit your options to a regular backup version probably.
