Seeking a reliable ATV for snow removal?

Hey there! I’m new so hopefully I’m posting within the right board. My father and I use a snow-blower to clear our large 3 lane driveway and long sidewalk around the property. The problem with the last few winters is that it snows hard in our area and it can be very wet. Our blower is large but simply won’t throw wet snow. We’ve decided to purchase an ATV and plow however we both know very little about ATVs. The model I have in mind is the base Polaris Sportsman 570. I need something that is easy enough for my father to operate when I’m not around to help him (he’s in his mid 60s with back problems so blowing + shoveling isn’t too practical anymore). My main questions however are:

1.) Will this be powerful enough to push at worst a foot and a half of very wet snow?

2.) How reliable will cold starts be? It’ll be kept in our garage all year round but it isn’t heated in the winter. (~20*F at the lowest).

3.) How long will this model last? We’re only intending on using it for snow removal during the winter. Nothing more, so can this be expected to last the next 8+ years with basic maintenance and little trouble.

4.) Is this a better option over the Honda 4×4 Foreman?

Sorry for the long post, thanks much in advance!
