This is from another thread, but might be relevant:
"I just bought this tractor. Since it is new, I cannot comment on its performance. I can write a novel, however, about trying to get some tire chains on the front wheels of this tractor.
It all started by asking the local John Deere dealer for the chains at the time of purchase.
The first response I got from the dealer was that for my purposes (150 ft driveway) I did not need them. I replied that having plowed that driveway in the middle of the winter for 30 years, I am very familiar with snow conditions in Mt. Shasta. I am also, like every normal human being, familiar with the fact, that rubber tires, without chains, slide on ice. Therefore, I pressed on with my quest.
My second response from the dealer was that placing chains on the front tire might void the warranty."
It's intuitive to think that most of the work should be done by the rear tires and the front tires only "help" the rear ones. If you place chains on the front tires (especially "only" front), the front end is doing the gruntwork, which is not built for. FWIW, I have a John Deere 4310 (4WD) and a 500 ft up-sloping drive way. I bought chains for the rear when I first bought the tractor and did OK in the first winter, then I added an 800lb
ballast on the 3 PTH plus antifreeze in the tires and took the rear chains off. That was 4 years ago, and sold them since I no longer needed them.
