Kubota MX5400 Hydraulic Leak Easily Repaired

This is a hands-on repair video, not a review: an owner walks through fixing a persistent hydraulic leak on his MX5400's loader valve plate, traced to a factory milling defect causing an O-ring to not seat properly. He shows the dealer-sourced replacement plate, disassembly, O-ring and fitting installation, reservoir refill using a sight glass, and a post-repair leak check. Useful mainly for MX5400 owners troubleshooting similar hydraulic leaks.

An individual owner documenting a real repair on his own tractor, sharing practical hands-on experience rather than dealership or promotional content.
