Just for clarity yours is the old model rtv 1100c and is a completely different animal from the rtvx 1100c. Try putting your machine in neutral engine off on concrete or hard level surfaces and push it by hand. It should roll fairly easy... if it doesn't then you most likely have a brake...

Just to clarify?? Your rtv stopped moving or at least was showing some transmission issues? The oil level in the hst was low so you disassembled everything?

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...

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

Atta Boy!

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...

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

If you want your RTV to last for many years and hours and still run when you get tired of it? My advice is as follows. change your hydrostatic transmission oil at least once per year and use kubota super UDT oil and OEM filters. Especially if you don't use it Hard!

Ok thanks. Fresh fluids i assume filters and kubota fluids? Dealer adjusted pressures to what? Silver metal on what plug?" Makes a huge difference ". Silver metal on the gear case magnet is normal as long as it isn't chunky. The suction filter should have been cut open to see what the hst...

Yes thanks. Now what is the problem with the machine? Please give the hour meter reading and miles? Any idea of service history?

First off since your machine is a 2015 it could be an x1100c or just an 1100c. Huge differences in the two so please confirm your model?? Maybe a pic?

Yes any wear no matter how insignificant will leak slightly and cause a decrease in performance. Fortunately the plates are relatively cheap. And considered a wear item.

I just looked at the api ratings on a bottle of kubota 15w40 diesel engine oil! That must be some really advanced oil.

That's a new one. Maybe should check the oil in the gearbox?
