My 570 plows just fine, granted we don't get much snow here in Indiana but seems like each year we get one above average snow. Only one time have we had enough snow my 570 couldn't get through but my neighbors 30 hp john deer got stuck that same day too. My drive is gravel, 700 foot, and has an S curve in it. Even when we have some 12-14 inch snow falls, (not real often) it pushes through just fine.
Also, I would reach out to MottoAlliance on this website. They have a Denali plow system which is easy to install, works good, and when I bought mine was very affordable. At the time mine was shipped to my house for under 1/2 of what my dealer wanted for the Polaris set up. They used to offer forum discounts and often times have scratch and dents for sale.
