Overview
A hands-on full-service video on a Massey Ferguson 231, covering coolant drain and refill (both radiator and engine block valves), fuel filter swap with air-bleeding steps, transmission fluid drain (revealing badly water-contaminated pink fluid), strainer inspection with missing hardware and metal debris, engine oil and filter change, battery tray powder-coat reinstall, air filter service, and full greasing. Goes deeper than a typical walkaround, useful for MF 231 owners doing their own maintenance.
