Kubota HST slipping diagnosis & fixes

[fieldOrange]

I'm having some trouble with the HST transmission slipping on my Kubota. I'm checking the fluid, linkage, and looking for any wear inside. Has anyone fixed this issue before or know the best way to handle it?

You were right to check the fluid and linkage. If you're still having slip issues even after that, it could be due to a worn charge pump or seals inside. If the easy stuff looks good, maybe try a pressure test next.

Hey, also take a quick look at the pedal return spring and neutral safety switch. If they're off, it can mess with the engagement. A worn charge pump or a blocked suction screen could also cause slipping when you're hauling something.
