Cast rear centers on john deere tractors

I am of the understanding that the centers with the bolt in hubs were made for both the A and B tractors. (Dont know if the G model was included)

The centers with eight clamps were used on the A and the ones with 4 on the B.

All Deere had to do was to to drill out another set of holes to make the centers interchangable.

I bought a set of centers that had 38" rims for my 39B. The hubs were cast in. I took the rims off, and 36" rims fit them as well. With-out knowing your casting number, you should look into it further before you take my word for it.

Good luck

I need new rims, also. It right now has 11-36 tires, and I am wondering if I could use 38 inch rims on my wheels. Does anybody have any ideas on that? I can't find any casting number on the wheel with eight studs, and the one with four studs has "T140" (if I remember correctly) cast on it.
