Worked well. We have ice now and NO WAY could I get by without them. Bad news is that the Polaris doesn't do nearly as well with only front chains as all fours.

This is only a short-term solution though. This summer I will keep eyes open for chains for all 4 tires at the auctions. If I can't find any decent used ones by fall, I'll be buying real tractor V-bars from tirechain.com for next year. I know there are several schools of thought regarding which tires to chain up and my gut feeling is I would rather have the rear end doing all that ripping and tearing than the front. So it will be ATV chains back on the four wheeler where they belong, v-bars on the rear of tractor and probably non-v on the front.
I'm not a tractor expert by a long shot but feel free to stalk me any time. We have been down almost the exact same road and I'll be glad to help if I can. And most importantly, if I don't know something, I won't BS you.
