Lets start using this thread instead of having to flip so many pages?

Thanks for the hours and miles. Seems that your machine would be at average 4mph and 6 hours a month and just a few minutes a day or it sits and gets used occasionally for longer periods of time. This is the perfect profile for transmission failure from oil not getting hot enough to boil out the water. The oil loads up on condensation and looses it's lubrication and corrosion,antifoam properties. I doubt you need a new transmission but the valve plates will be shot most likely and the rotory valve pistons need to be looked at for scoring. Not really that big of a job or all that expensive either. Kubota i think has new or remanufactured hast units for sale also or risk buying a used one off of ebay? But i would sure open up and investigate before i did much. Just advice

Thanks I’ll look into it. Is this something an average mechanic can do?

Thanks for the update, I have the HST fully installed, checking pressures and doing adjustments now.

Yes someone with basic skills and hand tools have done wonders. I would suggest that the brass valve plates be replaced with new though. They are important and don't really cost that much

No problem and good luck. Hopefully all you need is the valve plates but if the metal came from the hydrostatic and was magnetic and shiny i would think your valve pistons or possibly a bearing is bad. Look at Kiwi thread i posted to you ? He rebuilt successfully with mix and match parts and even resurfaced the plates!
