I used 4 link ladder chains on my 2wd Ford 4000 R4's for many years with no problems. Most of the cross chains covered both the inner and outer lug. Then I transferred the chains to my new MX5100 (with R4's). Most of the cross chains fell between the lugs no matter how I adjusted or tightened the chains. Comparing the tires on the 4000 with the ones on the MX5100, I noticed the lugs on the 4000 tires were well worn, were longer, and each pair of lugs made a narrower "v", keeping the cross links on the lugs. I now have duo-ladder combination chains on the MX5100. Much better, but there were still some cross-chains that fell between the lugs. For those I bought quick-links to pull them over the lugs. With hindsight, I should have paid more attention to the tires before getting the tractor. I think RoyJackson made the right decision with the turf tires. I'd probably opt for those if I had to do it over again. With chains they would probably be as good or maybe better than the R4's in snow, and obviously easier on the grass. I also had good luck with tirechains.com. Great chains and fast shipping.
I am having LESS THAN "good luck" with tirechains.com
I have two sets of tires & wheels for the little tractor; R4s and Turfs.
I have asked them repeatedly if there is a set of chains that would fit both sizes and about all they can tell me is this, copy/pasted from this morning's mail;
"Honestly,
I do not think it will work but you can take a chance and see if it works. We will not take any chains back that have been altered or taken apart. It is the risk you will take.
Best Regards,
Beth "
They seem unwilling or unable to dig out the specs on the chain sets for the two different tires sizes and compare them to make an informed suggestion/recommendation.
My SUBJECTIVE guess is that one size would fit both, within a link or two and that can be taken care of with a bungie cord.
The turfs are SLIGHTLY wider and a bit flatter, the R4s are a bit higher/taller.
I'm guessing that (as far as chains are concerned) these differences are likely to offset each other.
They can't or won't even tell me which set is bigger/longer.
BTW, the tires in question are 17.5L24 R4s and 44x18.00x20 turfs.
So if anyone else has been through this please reply.
I like them both, but it often happens that I have the turfs on JUST when I need to do some back-hoe work, chains could be useful at those times.
I try to use the R4s for winter and mud season, but don't always time the work and weather exactly right, so a set that fits both tire sizes makes so much sense (-:
