John Deere 3520 Annual Service

This is an owner's real-time annual service on his own John Deere 3520 at 181 hours, covering an oil and filter change, fuel filter swap, greasing the loader, checking tire pressure and axle fluid, and replacing a broken dipstick. It's unpolished and includes struggles (a stuck fuel filter, leaving the loader on by mistake), which makes it useful for seeing realistic troubleshooting rather than a clean how-to.

Posted by an owner-operator documenting DIY maintenance on his own tractor, including his own mistakes, rather than a dealer or professional mechanic.
