sgiggles :
I have a suzuki vinson 500 4x4 and I can plow some serious snow. I would suggest a four wheeler to plow any driveway, sidewalk etc. I simply put mine in 4 wheel drive, lower the blade and SHAZAM, I'm ripping thru snow and ice.
If you are planning on buying a new fourwheeler, try to negotiate one with snowplow installed. If not, you will be looking at $700.00 for the winch, pushtubes, plow etc.
Now, you can buy a cheaper fourwheeler that is a 2 wheel drive...I've had them myself ! I DO NOT LIKE A 2 WHEEL DRIVE 4 WHEELER, especially after owning a 4 wheel drive. I have had to use my 4 wheel drive on multiple occasions and it's never left me in a bind. These ATV's are being built to last these day's. I have a buddy who has over 8000 miles on his and it's just 2 years old.
Not only is a fourwheeler good at pushing snow in the winter, it is " dandy " at pushing other things like gravel, brush, etc. I have got some real good use out of mine and I believe you would enjoy having a playtoy around the house, they are so handy !
