Access and Inspect Additional Gearboxes

What happens here

The presenter opens a protective cover on the batwing mower to reveal its multiple gearboxes. He points out a second gearbox that lacks a dipstick, indicating that its oil level must be checked by other means (e.g., removal of a fill plug or an overflow method). He states that he will proceed to check all remaining gearboxes and lubricate all moving parts on the mower.

Goal: Verify oil levels/status of all gearboxes on the mower.
