Diagnose and Assess Gearbox Damage

What happens here

Examine the damaged gearbox of the haybine. The creator shows the gearbox, revealing significant cracking and breakage, confirming the severity of the failure. He explains that contacting New Holland revealed that a complete replacement gearbox is not available for this older model (implied New Holland 474), and individual components would be prohibitively expensive (around $800 just for the casing).

Goal: Understand the extent of the haybine's gearbox damage and part availability.
