<font color="blue">I did not want to spread wheels. However, for standard chains such as those on tirechains.com, you must add 1.5" flange to have room at inner fender. </font>
This actually is NOT the case with R4s on a
B2910, which is the same tractor as the
B7800 you have. It IS the case though, if one has turfs, which are a wider tire than the R4s. I have standard 2-link ladder chains on my
B2910 and they do work OK, although the clearance is close. Actually used them all year this year, with all the rain we were getting. Both mud and snow is not an issue. (I just realized I already said this in a post above, which I thought was in a different thread. /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif )

Murph,
While the 2-link ladder chains I got are better than no chains, I don't like them that much because about half of each cross link lays in between the lugs and is probably useless.
I would think a duro grip style chain would have to be a lot better. I couldn't find that style in my size when I was looking, and ended up with what I got. With turfs the ladder chains would work a LOT better than they do with R4s. That's my best guess anyway.
My neighbor runs ladder chains on his ag tires, and they are amazingly loose and if I had more clearance I would probably run my chains loose on my R4s and see what happened. But that is not an option for me, as the clearance is not there on my
B2910 Kubota.
The chains that Thisldoofarm got look pretty good in my opinion. They probably work a lot better than tight ladder chains on R4s like I have. I would not mind having a set of those chains. They do look a bit lighter duty than the 3/8 inch links on that seem common on tractor chains. I don't think I can spring for a set of them though, since I already have something that works for the most part, and especially since they are fairly expensive. Now if I did not have chains already, I would seriously consider them, as they look like they might give reasonable traction and maybe a smoother ride than larger link duro grip style chains would.
I hope I got it right when I am calling that style of chain "duro grip" ! /forums/images/graemlins/blush.gif
Some have reported that the duro grip type chains give a pretty bumpy ride compared to ladder type chains...
