Case-IH® Compatible Extended Wear Lower Clean Grain Auger (RH)
Enhance your clean grain delivery system with this premium C&M Australian-made lower clean grain auger. Specifically engineered for Case-IH® Flagship combine harvesters, this extended wear component features a specialised stepped flighting design where it enters the clean grain boot, ensuring a precise fit and smooth material flow.
Manufactured in our Griffith factory from heavy-duty Bisalloy 400 steel flighting, this auger is built to withstand high-volume abrasive grain flow. The use of premium wear-resistant steel provides a longer service life compared to standard factory units, keeping your grain handling system in top condition during intense harvesting periods.

Expert Maintenance Review
The lower clean grain auger is the primary transport for clean grain toward the elevator. Because it sits at the bottom of the clean grain system, it is often subjected to the highest concentration of abrasive material and moisture. We recommend inspecting the "stepped" flighting section that sits inside the boot, as this area often thins first, leading to reduced elevator filling capacity.
Upgrading to a Bisalloy 400 auger is a high-performance choice for preventative maintenance. This extended wear material resists the "sharpening" effect on flighting edges much longer than standard steel. This ensures your grain handling assembly remains at peak efficiency, preventing the need for mid-harvest auger replacements.
Maintenance Tip: Check the Boot and Bearings
When installing a new lower cross auger, always inspect the Clean Grain Elevator Boot for thinning and the Auger Bearings for play. A worn bearing will cause the auger to run off-centre, leading to uneven wear on your new Bisalloy flighting and potentially damaging the internal boot walls.
