I made a set of tire chains for my TO-35 tractor with 12.4/28 inch rears. They worked very well in snow, especially with the worn out lug type tires I had since they stood out on the tire, and helped on hard packed snow and ice too. I used standard oblong link utility chain, with no bars welded across. When I finally bought new lug tires, the chains tended to fall between the lugs, and weren't much of a help. Turf tires are flat enough so that chains will work. With good tires, my traction in snow is fairly good, but on hard snow or ice traction was poor. To address that problem, I put a couple of dozen sheet metal screws with hardened hex heads into the lugs of each tire, and my ice traction improved dramatically. I've left the screws in the tires year around, and they cause no problems.
