KONDEX KX7 CONCAVES FOR JOHN DEERE S, S7 & STS SERIES

Upgrade your John Deere S Series or STS Series combine with Kondex KX7 concaves — engineered for faster threshing, cleaner separation, and longer wear life than standard OEM concaves.

The KX7 system features two purpose-built assemblies:

• MaxThresh Concaves — Angled-bar design meets the crop head-on for immediate, aggressive threshing. Laser-cladded bars extend wear life well beyond traditional options. Place in the frontmost positions for earlier threshing and more separation as crop flows through the chamber.
• MaxRound Concaves — Optimized for separation and plug prevention. Heat-treated bars deliver a 25% improvement in wear resistance over non-heat-treated concaves. Always place behind MaxThresh assemblies to maximize performance.

Every KX7 concave is robotically manufactured and inspected by AWS-certified welders under an ISO-certified quality assurance process — built to meet or exceed expectations for fit and performance.

The result: less grain loss out the back, fewer cracked kernels at the elevator, and more flexibility to fine-tune your combine settings during harvest.
