A Closer Look at KX7 Concaves

MaxThresh™ & MaxRound™ — the Perfect Pair

KX7 MaxThresh concaves deliver a better, faster thresh than large-wire or small-wire concaves. This comes from the angled-bar design that meets the crop head on. This is more aggressive than traditional concaves, while our laser cladding additive both protects from wear and rounds the edge to soften contact. By placing MaxThresh assemblies in the frontmost positions, you’ll achieve earlier threshing that allows for more separation as your crop flows through the chamber.

KX7 MaxRound concaves also feature an angled-bar design to offer some threshing, though their main function is separation. They’ve proven very effective in preventing plugging, which in turn lowers rotor loss. With heat-treated bars, MaxRound concaves will not only outperform, but outlast traditional round-bar concaves. MaxRound assemblies should always be placed behind MaxThresh concaves to maximize separation.

Helping You Be More Productive

The angled-bar design of our KX7 MaxThresh and MaxRound box-style concaves meets the crop head on for more immediate threshing, which in turn increases the capacity of your combine. This allows you to raise your concave clearance, reduce wear to your rotor, and achieve more flexibility to finetune settings. With KX7, you’ll also gain more grain-on-grain threshing that results from increased airflow disruption.

Precision Product

All KX7 concaves are robotically manufactured, with welds individually inspected by American Welding Society (AWS)-qualified welders. Our ISO-certified quality assurance process includes rigorous visual and robotic testing to ensure each component meets or exceeds expectations for fit and performance.

KX7 MaxThresh concave assemblies feature a laser-cladding wear enhancement on the threshing bars to extend performance and life well beyond other high-wear options. MaxRound concave bars are heat-treated to gain a 25% improvement in wear resistance over non-heat-treated concaves.
