At the beginning of this year we got 48" of snow in 24hrs and it was a surreal time in our area. I was lucky that I had just purchased and installed ice chains on all 4 tires and had the rear facing snow blower on at the time. Otherwise I would have been screwed, like a lot of my neighbors. My next door neighbors have a dozer, excavator, tractor and skidsteer and they couldn't deal with the snow. The dozer was in a back field and they couldn't get to it, the skidsteer didn't have chains and was useless, the tractor had "H" pattern chains and they were useless. I ended up clearing their driveway going uphill while blowing snow. They were amazed at where my tractor would go and immediately ordered a set of euro ice chains for the their tractor. You should have seen the smile on the neighbors face when she first pulled her tractor out of the barn with the new chains installed. Then she put it to work and could not believe the difference those chains made.
They are expensive but I am very glad I spent the money. Not saying everyone should have them or needs them but for my conditions it was one of the best purchases I have made for the tractor.
