Tractor oil change; How to change oil in a John Deere 5520 tractor

This is a hands-on walkthrough of an actual engine oil change on a John Deere 5520, not a general maintenance overview. It shows exactly where the oil filter and drain plug are located (warning about nearby transmission/hydraulic plugs), the socket size needed, approximate oil capacity, filter installation technique, and correct filter orientation, finishing with a real fill-level check after startup. Useful for owners doing this specific job themselves.
