Keith in Alberta,
I like your set up. I do not doubt that you receive the lionshare of snow where you live, but I would say I love your X series machine for snow. I have had the following tractors: an X485, 595, 4310, 3720x2, 4520, and 2320 and believe it or not we receive a goodly amount of snow each winter. Our situation is worsened by the fact that there is not one inch of flat ground where we live and we usually get heavy wet snow. Of the tractors I mentioned the best machine I had for pushing snow was the 595, by a mile. On our hillsides, it would work circles around my 4520 which was roughly akin to plowing snow with a schoolbus. The reality for me is that compact tractors with R4 tires just do not move snow well unless it is perfectly flat or one is using chains.
