How to Change Engine and Hydrostatic Oil On The John Deere 4066R

This is a real hands-on DIY session on a 4066R, not a talking-head overview: the owner removes front panels, drains and refills engine oil with a new filter, checks the oil pressure light on startup, then drains and refills the transmission/hydrostatic system (12.4 gallons) using a John Deere filter service cheat sheet with actual capacities. Good for owners planning to do this exact service themselves and wanting real step-by-step visuals.
