How to change the oil on John Deere 3520 tractor

This is a real hands-on oil change on the owner's own 3520 cab tractor at 1200 hours, not a demo. It walks through draining the pan, pulling the filter with an oil filter wrench, priming the new filter's seal with fresh oil, refilling via the dipstick, and adding Lucas oil stabilizer. Good for owners wanting a straightforward, unpolished walkthrough of a DIY oil change on this specific model.
