my buddy plows with a yamaha timberwolf 250 2 wheel drive works ok not great but you need to keep the speed up depending on how deep the snow is...hes not running chains either so im sure that would be a plus..he made his blade out of a lawn tractor blade pretty heavy for the machine but it can be done..good luck..
Just got finished outfitting a 95 Polaris 400 4x4 automatic, with high, low, reverse. Spent $400.oo on the plow, $ 50.00 to "adapt" a buyers spreader. All total got $3500.00+/- in it. And to be honest with you, I agree with the above post, you can probably use a 2wd. Just 2 things to think about, weight of plow in relation to quad weight, make sure it is up enough, the blade, to clear for loading, unloading. Also is it auto or manual, the pressure on te trans will be a little greater because it is 2wd. I used 2 spacers on ech front strut to brin the blade up.
Hope this helps.
