Servicing John Deere 3 or 4 series! John Deere4066R service #630

An owner-operated full-service walkthrough on a John Deere 4066R covering radiator and air filter cleaning, engine oil and filter changes (with a candid note that the manual's stated oil capacity runs over), fuel filter service, cab foam filter, greasing fittings, and tire pressure. Runs about 19 minutes with real hands-on tips and workarounds. Most useful to 3- or 4-series owners tackling their own routine maintenance.

An owner-operator sharing hands-on service experience from their own 4066R, with no apparent commercial affiliation.
