Case-IH® & New Holland® Compatible High Capacity Vertical Unloading Auger

Increase unloading performance with this premium high-capacity vertical unloading auger, designed as a direct-fit replacement for selected Case-IH® Axial-Flow and New Holland® CR Series combine harvesters. Featuring hardened 8-spline drive hubs and Wear-resistant flighting, this extended-wear auger delivers exceptional durability and reliable grain handling in demanding harvesting conditions.

Manufactured with heavy-duty 6.3 mm left-hand flighting, this vertical unload auger is dynamically balanced to reduce vibration while maintaining smooth, high-capacity grain transfer. The abrasion-resistant Hardox® steel provides significantly improved wear life over conventional mild steel flighting, helping reduce maintenance costs and maximise uptime during harvest.

Expert Maintenance Review

Vertical unloading augers are subjected to high loads and continuous abrasion during grain unloading. Inspect the flighting for thinning, excessive wear, cracks and damage around the spline hubs. Worn augers reduce unloading efficiency and increase stress on the unloading gearbox, bearings and drive components. Replacing the auger before significant wear develops helps maintain fast unloading speeds and reliable machine operation.

Installation Tip

When replacing the unloading auger, inspect the upper and lower bearings, gearbox, drive couplings and spline engagement for wear. Correct alignment and proper bearing condition will maximise the service life of the new auger and ensure smooth unloading performance.
