I didn't buy the Wix to save $2.50! I wouldn't spend $10 plus/quart on oil and then intentionally skimp on the filter. My belief (and admittedly I could be wrong) is the Wix is a premium filter that it's at least as good as, and likely better than the Kubota filter. I don't know who makes Kubota filters (pretty sure Kubota doesn't make them). I know Fram and other filter manufacturer's nowadays use some pretty low quality filter media. My belief is Wix uses premium materials. I felt the same way about the Amsoil vs the Kubota oil.
If anyone knows otherwise, I'm always open for improvement!
Take a good look at the OEM Kubota Hydrostat filter. You will note that the filter base is machined aluminum. No, I have no idea why, but the filter is definitely not low cost.
Hydrostat transmissions are built to close tolerances (closer tolerances than is the engine) and do not well tolerate incorrect or dirty oil.
I'll stick with Kubota filters and SUDT.
