I bought the Glacier system from my polaris dealer. They have up to 60" blades, v-plows, county plows, my setup was right around $400. The blade is a snow/dirt blade so I would imagine it is rather heavy steel, but I couldn't tell you the guage, I just know that I tried to lift it by hand to move it detatched from the bike and it was a bit of a workout.

 

fishertown, i boughtmine at creekside powersports.com. with 2wd AND tire chains you should be ok. the plow was 385 to my door in about a week. you should probably drop your tire pressure down to about 3# that helps with traction too. just be carefull how fast you drive down the road if you go to plow someone else out. the combination of heavy wight and low tire pressure and wind on the blade can make it a real handfull.

 

Blackline....the only way to go. Heavy duty....and it has its own lifting motor so you don't have to constantly wreck the cable on your winch or have it fail in the middle of a night of snow plowing. Check one out personnally and you won't believe the quality of it compared to the cycle country. It will actually lift the front tires of your quad off the ground if you adjust it with that much lift. Plenty of downforce to say the least, but I did have to put highlifter springs on my Griz to stop the springs from absorbing all the movement when lifting the blade.
