Case-IH® Compatible Wide Wire Concave Position 2 & 3
Optimise your threshing and separation efficiency with this high-performance aftermarket wide wire concave. Specifically engineered for Case-IH® Axial-Flow combines, this concave is designed for Position 2 and 3 fitment. Unlike the lead concave, this unit features a standard flat frame (no ramp) to facilitate consistent crop flow through the secondary threshing zones.
Manufactured from premium materials and fully heat-treated, this concave offers superior abrasion resistance compared to standard units. The wide wire configuration is specifically designed for high-capacity separation of corn and beans, ensuring maximum grain recovery. This extended wear solution ensures your threshing assembly stays in top condition for a significantly longer service life.

Expert Maintenance Review
While the first concave handles the initial impact, the concaves in Positions 2 and 3 are critical for complete separation. Over time, the cross-bars in these zones suffer from abrasion thinning, which can lead to grain "carry-over" and losses out the back of the rotor. We recommend inspecting the bar height and wire integrity during every preventative maintenance check to identify worn components before the harvest season begins.
Upgrading to this heat-treated wide wire concave is a strategic choice to save money by ensuring maximum grain capture. The high-strength frame resists warping under heavy crop loads, keeping your threshing system in top condition. This investment provides a significantly longer service life compared to non-heat-treated alternatives.
Installation Tip: Concave Leveling
When installing new concaves in Positions 2 and 3, it is vital to re-level the concave frame to the rotor. An unlevel concave will cause uneven abrasion and lead to grain damage. This is the ideal time to check your rotor rasp bars and separation grates to ensure the entire threshing circuit is restored to maximum efficiency.
