He speculates about whether it needs periodic fluid service and whether there's a drain, but doesn't answer the question or perform the service. Useful mainly as a heads-up that these hubs exist, not as a how-to.
Posted by an owner sharing an in-the-moment discovery on his own tractor, not a mechanic explaining the fix.
The owner found a vent or fill plug on the hub after a blowout and thinks fluid may need checking or changing, but he does not confirm a service schedule.
The owner is unsure and asks if the plug he found could also serve as a drain, but the video does not answer this.
