On my 8N, I had loaded R1's, chains, and a rear blade. I had to run chains on this tractor when clearing snow. Almost unstoppable, but it marked our asphalt driveway up pretty good. On my L3940 with turfs, I only use a rear
ballast box and front blade only. For some snows I do not even engage 4wd. My turfs are very aggressive looking with deep tread and lots of sipes. No chains are needed. They perform in dirt for FEL work very well also. If I get into sloppy mud, there is a better tire choice, but for my uses, they have served me well. Philip.
