This pin secures components within the pick-up drum assembly of a forage harvester or similar harvesting machine. It acts as a locating and retaining element, transmitting shear loads between the drum and the attached tine or scraper components. A worn or sheared pin causes the tine to loosen, leading to uneven crop pickup and potential damage to the drum body. The manufacturer produces this pin to match the original part's hardness and diameter, ensuring it shears at the intended load to protect the drum from overload. On installation, verify the pin is fully seated and that any retaining clip or fastener is secure.
