John Deere 4 series Grease Zerks and Fuse boxes... where are they?

This is a narrow, practical maintenance video, not a review or walkaround: an owner walks around a John Deere 4044M pointing out every grease zerk location (loader connections, arms, front axle) since the closed system removed old wheel-well zerks, then shows both fuse box locations and recounts diagnosing a blown fuse that killed their LED lights and third function switch. Best for existing 4-series owners doing routine grease and electrical troubleshooting, not shoppers.

Appears to be an owner-operator sharing hands-on maintenance findings from their own tractor use.
