I've also owned a 2008 Polaris Outlaw 525IRS with full FMF exhaust and Jet kit. Loved that quad. Would buy again. Smoked my buddies Raptor 700 all day long.
I've been using Zilla's for the past couple of years and they have been working just fine. When I had a plow on our 2005 Sportsman ATV we had just the stockers and they didn't like the deep snow too well.
Didn't think the Polaris one was that much. I think I paid $350.00 for the blade and $180.00 for the mount. That was a couple years ago. Ofcorse I already have a winch. I have seen way more expensive systems out there.
We have the Polaris Glacier II on our 2012 RZR 800. Works great! It goes on and off in 15 sec. so we can go riding. Never had an issue pushing lots of snow with it either. Your ranger would be even better suited for plowing. How much snow do you need to move?
