John Deere 3320 Changing hydraulic fluid and filter # JD Tractor

This is a real owner performing his first hydraulic/transmission fluid and filter change on a 2013 JD 3320, shown step by step: locating the drain plug and filter, draining nearly seven gallons, comparing old versus new filter condition (metal specks visible), refilling via dipstick checks, and bleeding pressure from loader and three-point hitch. It also covers sourcing parts online versus dealer pricing. Good for owners planning this same DIY service.
