Kubota B7800 service

This is a full hands-on service walkthrough on a Kubota B7800, not a quick overview. The creator heat-cycles the tractor, changes engine oil and both filter sumps, swaps the air filter, replaces the fuel filter (showing water contamination inside), services hydraulic fluid and its two filters, and blows out a badly clogged radiator, calling out specific part numbers throughout. Best for owners planning to do this exact service themselves.

Appears to be an independent mechanic or hobbyist documenting real maintenance work on a customer's tractor, with a practical, unscripted, DIY-instructional style.
