Jeff,
I don't know but your best bet is calling a Kubota dealer and asking them.
Kubota changes bolt patterns by fractions it seems on every model they
make in my experience. Or you could measure the bolt patterns on both to
know exactly what they are, and don't forget to measure the back spacing
( distance between the center plate on the back side to the outside of the
wheel lip ) so there isn't a clearance problem too.
If you're dealing with someone trying to sell them that's to far away to be
practical to go do it yourself, you could always have them put a piece of
cardboard on the back side then use a pencil to trace the pattern including
the center hole to because that's another point critical for fit.
