OK I just posted a few questions in a different thread but thought this was different enough for it's own. I'm planning a doing some snow plowing, and I never did this before. I'm ready to hang up the snow shovel. I've seen where others recommend wheel weights and chains for plowing but is that a necessity for plowing? I am just trying to figure out all that I would need. Could I get away with plowing for a year or so without them (if need be) and then get them when I can afford it? Another thing, would the AG tires in the back work as good as chains in the snow?
