Kubota B8200HST. Loses drive power.

Transmission fluid was universal grade bought from John Deere dealer, level is okay.

Lose speed both forward and reverse.

Any change on the hydraulic and PTO functions. Do they operate as they should?

If loses speed and power in both directions and also gets hot quickly points towards either the pump or motor leaking. Do you have the ability to install gauge in the HST pressure ports. Not sure if Kubota supplied ports for this or not. Pressure dropping as the oil warms would also indicate an internal leak.

Hi all, changed transmission fluid, filter, removed lower sludge filter, getting it back on damaged thread so had to get a new one. Now all back together is somewhat better but going up even a slight slope it struggles. Guess it is 30 years old or so and don't know any previous history. To be safe I changed the fuel filter, loads of rubbish and the engine oil/ filter, air filter. Don't know if I'm just throwing money away now or missing the problem.

I had trouble with my B8200 HST losing drive power after running for awhile. I changed fluid and filters several times sent to dealers twice they couldn’t find the problem. Finally it ended up being the small hydraulic pump on the right side of the engine. It supplies all the fluid to the transmission. That corrected the problem. But I’d change fluid and filters first and clean the screen
