Hi to all, new to this forum, I am located in the Cadillac Mi area and get considerable snow to deal with in my 1/4 mile long driveway. so far my JD 210 with a 37A snow-thrower has handled this job, but the k241 is underpowered in heavy snow, I am looking at case 400 and 4000 series tractors with much interest. I have kinda ruled out the 444 as I believe it would have the same problem as my JD 210, so I am looking at the 446 and the 448 but have found a couple of 4016 Ingersoll tractors. My question is what is the difference between the 446 and the 4016? any other insight or suggestions would be greatly appreciated, thanks milkman
