Update: Replace the Kubota wheel/tire and used correct spacers
Posted By RichC on July 14, 2026
The additional parts for the Kubota Zero-Turn mower (correct sized SS spacers) and replacement solid wheel (broken zerk) arrived last week, so decided to spend part of my weekend taking things apart and putting them together again. The new spacers fit much better but I did add a couple copper washer shims, which was probably a good idea anyway?
Only time will tell IF this modification will last, but I do know that these new solid rubber wheels are not nearly as comfortable (harsh ride on a rough lawn) as the air filled originals … nor are they nearly the quality of wheels and bearings that have lasted 20 years. Nevertheless, so as long as I take the weight off the front when parked (flat spots), I think this will prevent the ongoing punctures and deflation problems. Big picture, it was a small investment and I can always buy the original $$$ parts and go back to air filled tires and wheels with premium bearings.
I have a second solid wheel, but do I replace the other side … or wait until something fails on that side too? Brenda said I need to replace the other one so they match … because “it doesn’t look right.” 😉
