Keep your grain handling system moving with this C&M aftermarket clean grain elevator chain assembly, built to suit selected New Holland® TR Series Twin Rotor combine harvesters. Also known as the main grain chain, this assembly elevates threshed grain to the grain tank and is a critical wear component in the harvesting system.

Assembled by Collier & Miller in Griffith NSW, this replacement chain is manufactured using quality CA550 chain, waterjet cut paddles and high tensile fasteners. It is supplied ready to install with the same paddle spacing as the original chain, helping restore reliable clean grain elevator performance in the field.

Expert Maintenance Review

Clean grain elevator chains work in a high-load, abrasive environment. Over time, chain stretch, worn paddles, loose fasteners and damaged links can reduce elevator efficiency and increase the risk of blockages or grain handling issues. Inspect the chain before harvest and replace it when paddle wear, chain elongation or link damage is evident.

Installation Tip

Before fitting the new chain, inspect the elevator sprockets, bearings, tensioners and housing for wear or sharp edges. Replacing a worn chain onto damaged sprockets can shorten service life. After installation, rotate the elevator by hand where possible and confirm the paddles clear the housing correctly before operating under load.
