I bought my Kodiak originally for hunting, but the dealer had a great combo deal with winch and plow so I bought it. For me it worked so well that I bought the Grizzly. The Kodiak is a 400cc auto, 4X4, I plow in low range, and don't really have a problem until about 8-9 inches powder or 5 or so of wet. My Grizzly just eats the snow up. It is a 660cc, auto, 4X4, with factory front locker, I also run 27X12X12 Blackwater XT's front and rear (takes a little power away but worth the extra traction), also the 300 lbs of salt and 50 lbs of spreader make great ballast and help tons with traction. Not to mention that it help cut down the time since I can plow and salt in one pass most of the time. With this set-up the Griz will push snow until it boils over the blade and still keep going. I also use them for plowing a couple of small drives when we only get a couple of inches, instead of Bobcat.
We use a Honda Foreman with a cycle country 48" blade. We put a u edge on the plow and it makes all the difference when doing city walks - the blade doesn't trip and it's quiet.
Our biggest logistical issue since the 4 wheeler makes such quick work out of the sidewalks is deciding where to send the 4 wheeler and transporting it from location to location. Ideally I'd be someplace with it for hours - but instead we move it around to the accounts we do have and it makes quick work out of walks.
This last storm we had officially 10.2" (melted down slightly to 7 to 8") and we pushed our walks twice. Since many of our city walks are right against the city streets we are often plowing road slush junk. The 4 wheeler goes right through it. We used to use a snow blower or hand shovel - and now, this 4 wheeler is a God send.
my kid just broke her leg on my polaris xplorer 400 4x4 2stroke on xmas day. just took to dealer and 900.00 later I have my #1 snowblower back. I am just thankful that the only thing that my kid broke was her leg she learned that a 900lb 4wheeler can not take down a twenty year old oak. any way this is my first year of haveing it and this kid loves how much time i can save on my lots and walk with it. Is long as i am pushing snow i well have one.
