John Deere 3043D First Hydraulic Oil Change + Filters

This is a first-timer's hands-on hydraulic fluid and filter change on a 3043D with 300E loader, shot from underneath the machine with real tool sizes (1-1/4 wrench), the drain plug and magnetic plug inspection, metal flake in the old fluid, filter swap with pre-lubed O-ring, and a rough cost estimate of $300-$350. Good for owners doing their first DIY hydraulic service and wanting to see what worn fluid and a used filter actually look like.
