I have seen a lot of good advice here. In just looking at some of the messages, I have not seen much on the snow plowing aspect. IMHO, a lawn tractor suitable to cut just an acre, may be ok for dry, powdery snow but not for anything heavier. I'd talk to the neighbors and find out what works for them. If the ATV works for snow, I'd keep it. My very limited experience with snow says you may want a walk-behind or tractor mount snow blower.
