Full service on my John Deere 4320 #44

This is a hands-on owner-performed service session on a John Deere 4320, filmed at 2444 engine hours (104 hours since last oil change). It covers engine oil and filter change with socket size and fluid notes, hydraulic fluid drain and refill using a manual pump, fuel filter swap, a cabin/condenser cleaning, and a startup check afterward. Good for owners wanting a real-world walkthrough of routine annual maintenance steps and timing.

Appears to be an owner-operator documenting routine DIY maintenance on their own tractor, with a casual, unscripted, non-sponsored tone.
