I live in the western new york area and own a John Deere 4510 and use it all year around. One of the things that I found is that it is a little "light" and wants to slide while mowing on the side hills and around my pond. After moving the tires to the outside position, it offered a lot more stability. I run R series industrial tires all around with chains only on the back. Chains will grab just about anything but you need a little "give" when running 4WD in the woods to haul out logs for fire wood. I live on a south facing hillside and plow about 750ft of gravel drive way, the chains help a great deal down at the roadway when the road and driveway ice up, my JD1010 2 WD tractor with no chains , does nothing more than polish the pavement once it ices up. I suspect your turf tires will have the same problem. One thing to check though, make sure that there is enought clearance between inside of the fender well and the tire. I run field chains and it is pretty close to the fender well. I am not a fan of cc filled tires, only because of what I have seen the damage done with the inevitable leaks. As far as using a "scraper" to plow out your drive way, I am not sure if you are referring to a scraper blade or a box style scraper. The scraper blade is the least expensive way to go, but you will find it of limited use without any down pressure or weight. If you haven't bought the blade yet, you might consider purchasing a box style scraper. The box style weighs more and is a lot more versatile and costs only couple of hundred dollars more. I use my box style scraper most of the year, putting a 6 ft 2 stage blower on for the winter. I find the box scraper most usefull when hauling logs out of the woods, instead of dragging the logs with the drawbar . I have chain hooks welded onto the bar that runs from side to side, this allows you to chain hook the logs to the bar arnd transfer the weight of the log end to rear wheels with the 3pt hitch. It also keeps most of the log from picking up the rocks and mud that destroy the chainsaw chain. I have had 2each 18" dia. by 40 ft ash logs hanging off of the box scraper and pull very nicely over 1000Ft out of the woods. One thing I might suggest for plowing snow, find a old snowplow blade , usually a $100 by the roadside, and attach it to your front bucket. If you don't have the bucket, you will need to fabricate a frame to attach it to your tractor. I only mention it because I got bad crick in my neck , turned around watching where the blade goes when you are plowing snow. Sorry about being long winded, hope the suggestions help.
. BTW used an 8N(vintage 2WD tractor) on a 200' driveway w/ 10% average slope with a rear blade no chains for years. with the wet snow weight added to the blade helps
