John Deere® Compatible High Capacity Clean Grain Cross Auger
Maximise your grain handling efficiency with this premium C&M Australian-made high capacity clean grain cross auger. Specifically engineered for high-output John Deere® STS and S-Series combine harvesters, this lower clean grain auger assembly is a heavy-duty replacement designed to maintain peak throughput in high-yield conditions.
Manufactured in our Griffith factory, this auger features Bisalloy 400 flighting, providing superior abrasion resistance compared to standard factory units. The use of high-strength wear plate ensures an extended service life, keeping your grain delivery system in top condition and reducing the frequency of mid-harvest auger failures.

Expert Maintenance Review
The lower clean grain cross auger is a critical wear point located at the base of the cleaning shoe. Because it handles the full volume of threshed grain, the outer edges of the flighting can thin rapidly, leading to a significant drop in elevator loading speed. We recommend inspecting the flighting thickness and checking for shaft straightness during every preventative maintenance check.
Upgrading to a Bisalloy 400 auger is a high-performance choice to **save money** on long-term maintenance. The extended wear material maintains its effective diameter much longer than carbon steel, ensuring your grain handling system remains at maximum capacity. This balanced assembly reduces harmonic vibration, protecting your 35mm and 25mm bearings from premature failure.
Installation Tip: Check the Sprocket
When installing a new clean grain cross auger, always inspect the 10T x 45mm drive sprocket and the chain for wear. A worn or "hooked" sprocket will place uneven stress on the solid shaft, potentially leading to fatigue. Replacing the sprocket alongside a fresh auger ensures a high-strength drive connection for the entire harvest.
