Kubota X1140 Hydrostatic transmission problems

In this video, I walk through a real issue with a Kubota RTV-X1140 where the hydrostatic transmission isn’t driving properly. The machine builds pressure, but won’t pull its own weight once the parking brake is released — a frustrating problem that can point to several internal or external issues. I break down: 🔧 Symptoms of a failing hydrostatic transmission 🔧 Checking relief valves, charge pump, and pressure issues 🔧 What happens when it drives with the brake on but not off 🔧 Possible causes like worn components, internal leaks, or valve problems 🔧 Real troubleshooting steps you can follow before tearing it apart Whether you’re dealing with weak drive, no movement, or pressure loss, this video will help you narrow down the problem and decide your next move. 👇 Drop a comment if you’ve seen this issue before or have questions — I’ll try to help!
