John Deere 4400 engine oil, hydraulic oil, and air cleaner change.

A hands-on, step-by-step walkthrough of a full fluid and filter service on a John Deere 4400: draining and refilling hydraulic oil (with drain plug location and filter replacement), changing engine oil and filter, and swapping the air filter's inner and outer elements. Includes tool sizes, rough fluid quantities, and practical notes like the hidden hydraulic mesh screen. Useful for an owner doing this exact maintenance themselves.
