Joined here to get some answers, no one around hhome seems to be of any help, even the dealer if you can believe that. I have a Kubota BX2350 that I mow with and scrap the driveways, gravel. I was working on a parking area for our motor home and I noticed that it didn't want to pull in reverse very well so I put it up in the building. Got it back out to mow the yard and it doesn't want to pull forward or in reverse. .Pulling the slightest incline is a struggle and if the front wheels are turned, you will have to go to low range. I changed the fluid, Super UDT, and a Kubota filter, soaked the screen over night in carb cleaner and cleaned it good before installing and it didn't change a thing. The fluid that came out wasn't bad, no burnt smell or nothing. Lift and P/S work great so I'm assuming there is a second pump for the hydrostatic. Any ideas? Keep in mind I know nothing about these, I've worked on cars, diesels and everything else my whole life but never touched one of these.
