My kids and I have about 25 hundred feet of private drive which is up and down the hills. We have a four wheel drive 65 hp farm tractor and a 23 hp 4 wheel drive Kubota but we have found that our four wheelers do the job so much quicker and safer. even with chains on I have had problems with the tractors but the four wheelers just keep right on going. They move so much faster and keep the snow rolling off the blade with very little effort. I have a 60 inch blade on a 500 Honda Rubicon. I have plowed as much as 18 inches of snow. The first time through that was a little rough.
