I actually took a reamer and cleaned out the holes for the studs and they were still visibly off. The hub was about 1/8" too big which is more than could be accounted for by paint. I did look at that though. I must have gotten a screwed up set.
I would just have the dealer order another set, and take that set by and have them try to mount them on another tractor just for kicks. Might not be machined incorrectly, could be for another tractor; even another manufacturer.
Does anyone know if the Kubota spacer kit is compatible with the mid mount mower on the new B series tractors (B2620) ? I'd like to get it for additional stability when mowing - already have loaded tires, but have a lot of steep hills.
I think the spacers move the wheels out about 1 1/2" on each side. Usually the problem is the rear anti scalp wheels on your mower deck. If there is more than that much clearance on your present setup, you should be all set.
