Can't really answer your question, but, here's what I did. I was trying to chain up all fours on a 4100. There was not enough clearance between the turf fronts and the steering mechanism to apply chains. So I settled for the rears only. But it was tight clearance in the rear also, so I called my local TSC store and they ordered truck tire chains for me. They are nice compact links, not overly heavy. But still do a great job. I had to cut them down to size a little, but it was easy. If you try to do this, have both the metric and english size numbers with you, they will have better luck finding compatible chains. Peerless Chain manufactures many truck and tractor chains and TSC can order them. Good luck!
