John Deere 3520 First service part 1

This is a hands-on owner video showing the prep work before a first service on a John Deere 3520 at 127 hours: removing the quick-attach loader and auto-connect mower deck, capping hydraulic lines, warming the engine, and laying out new parts (oil filter, air filter, fuel filter, oil). It ends as the actual oil drain begins, so it's most useful to owners wanting to see teardown steps rather than the full service itself.
