Kubota BX 25 Wheel spacers, Would either of these work? Bore size confusion.

[JOE G]

Hi, I am have been doing a lot of research and it appears people use both of these, I see one is 70.5 MM Bore and one is 71.5 MM Bore. It is not 100 % clear to me which is for the BX 25 as I see a lot posted about the BX 23. I am not sure if they use different sizes.

Also Should I go with 1.5 or 2 inch? I do not use the mower. Just the loader and Backhoe.

Thank you

The bore size won't matter as far as putting the spacers on the tractor, because the BX setup is lugcentric, and has no center hub that the spacer has to fit over.

So the only question comes down to the diameter of the hole in the wheel, which does not matter if the hole larger than the hub protrusion of the spacer.

I put spacers on my BX2200, and my son in law put 2" on his BX23s. I saw a recent thread at OTT I think where a guy found 3" spacers on Amazon that fit his BX. I don't recall our worrying about the hole size in the wheel. BUT it is a valid concern.

For safety wider is better if you are dealing with side slopes.

The never ending debate is how much stress is involved when spacer width is increased, and what the risk is in using spacers. I decided I would rather break my tractor than my neck, and put 4" spacers on my B2910.

I was originally thinking about the 1.5 but now I am thinking of going with the 2"

I ended up getting the 2 inch spacers, they fit on the tractor fine, Will need a thin wall socket to get the factory bolts tightened . I have not mounted the rims yet as I am doing some maintenance.

You will be happy with the results. I have had 2 in spacers for many years now, no problems with my BX .

So I got the 2 inch installed and I tried them out, I would like The inside/Center hub of the rim fit a little tighter on the center of the spacer, I did not use this tractor with out them as I just got this tractor and I am just going though it but I tried it with these and it still is a bit unstable compared to my other tractors. I would say this is a must have if you are using these for anything other then mowing.

The BX design is lugcentric, so there is no protrusion of the hub to fit into the hole in the wheel.

If the spacers you got are hubcentric like the ones I have, they will have an extension on the outside that would fit into a second set of spacers, if you feel the need for more stability. I have not done this, but did check my spacers before installation to see if this would be the case, and it is...

Being hubcentric, the spacers would lock together well and not depend on the lugs for centering...
