Case-IH® Compatible Wide Wire Concave Position 1
Optimise your threshing performance with this high-performance aftermarket wide wire concave. Specifically engineered for Case-IH® early and mid-series Axial-Flow combines, this concave is dedicated for Position 1 fitment within the product feeding and threshing zone. It features a precision-welded intake ramp and a structural integrated extension, providing a high-strength foundation for your machine.
Manufactured from premium materials and fully heat-treated, this concave offers superior abrasion resistance compared to standard units. The large wire configuration (12 wires) is specifically designed for the efficient separation of corn and beans, while the single-piece construction eliminates the "flex-fatigue" often seen in bolt-on designs. This extended wear solution ensures your threshing assembly stays in top condition for a significantly longer service life.

Expert Maintenance Review
The concaves in the product feeding transition area take the brunt of the initial crop impact. For corn and beans, abrasion on the cross-bars can lead to grain damage or poor separation. We recommend inspecting the concave wires for "bowing" and checking the intake ramp for thinning during every preventative maintenance check to identify worn components before they cause mid-season downtime.
Upgrading to this heat-treated wide wire concave is a strategic choice to save money over the life of the machine. The single-piece frame maintains its alignment far better than multi-part versions, ensuring your threshing system remains in top condition. This investment keeps your product feeding system efficient and provides a longer service life in high-capacity conditions.
Installation Tip: Feeder Transition
This concave is designed specifically for Position 1 fitment. When installing, ensure the integrated intake ramp aligns perfectly with the feeder house floor for a seamless product feeding transition. This is the ideal time to check your feeder house slats and front rotor intake flighting for wear to ensure maximum throughput in heavy crops.
