Stewart Steel FloThru 3ft Unload Auger Extension (14" Case-IH & New Holland)
Maximise your harvesting efficiency and safety with the Stewart Steel FloThru 3ft unload auger extension. Specifically engineered for Case-IH® and New Holland combine harvesters equipped with a 14" unloading system, this high-performance add-on provides the critical extra reach required for modern high-capacity grain handling operations.
Manufactured in Canada, the FloThru system is a professional-grade solution for operators needing additional clearance between the combine and grain carts. This 36" (3ft) extension effectively increases the discharge radius, allowing for safer unloading on the move and reducing the risk of collisions. This strategic upgrade allows you to extend the capabilities of your current machine, maintaining top condition and providing a longer service life for your unloading circuit.
Spout Specification
This extension kit is compatible with Fixed Spout configurations only. Please note it will not fit machines equipped with adjustable or pivoting spouts.

Expert Maintenance Review
The unload auger extension is an essential upgrade for modern headers, as it keeps the grain cart at a safer distance. However, the additional 3ft of length increases the load on the vertical unload auger and the primary drive pivot. We recommend inspecting these worn components for stress or fatigue during every preventative maintenance check to ensure the drivetrain remains in top condition.
Choosing a FloThru extension is a strategic way to save money and improve efficiency. The high-strength internal flighting ensures a continuous and high-velocity grain flow, while the extra reach prevents downtime caused by accidental contact between the header and the cart. This high-performance add-on ensures your unloading system achieves a longer service life even in high-yielding crops.
Installation Tip: Flighting Alignment
For high-performance results, ensure the extension flighting is perfectly timed and aligned with the original 14" auger flighting. Any gaps or timing offsets can cause grain damage or "slugging" at the joint, placing unnecessary stress on the drive system. This is the ideal time to check your unload auger gearbox oil levels to support the increased operational demand.
