Koyma Klad® High Performance Shear Bar (to fit Claas® 491-497 series)

The K900SHBR shear bar is specifically designed to fit Claas® 491, 492, 493, 494, 496, and 497 series harvesters. It acts as a stationary cutting point for the cutter drum knives, providing exceptional durability and precision when cutting in hay, corn or any other crop harvesting.

Crafted with a laser-applied welded carbide material, this shearbar boasts a high-performance cutting edge that undergoes extensive testing to ensure superior wear resistance and strong bonding. The carbide overlay is carefully ground down using a diamond stone to maintain a sharp, long-lasting edge, offering higher performance compared to standard OEM shearbars.

Key Features:

• Reversible Design: The shearbar is designed for easy flipping, allowing users to rotate it for maximum lifespan when entering a new silage forage season.
• Hardware Kit Available: The K980BK hardware kit ensures you have all necessary components for a smooth installation and operation.
• Replace When Edges are Rolled: Inspect the shearbar regularly, especially when the edges are rolled, as this indicates the time to replace the bar for optimal performance.
• Stationary Knife/Ledger Bar: Ensures precision cutting by providing a solid base for the cutter drum knives to cut against.

Wavey Shear Bar Option: 

The Kooima Ag patented wavey shear bar K494DSW features a unique wavy design that holds material in place for a more consistent cut, reduces wear on the knives, and enhances overall performance.

Customer Testimonial

"I have one of your hard facing shearbars, it is one of the best things I have done. I chopped a lot of whole corn since fitting your shearbar and haven"t had any problems with the shearbar bolts breaking. The main thing is my blades are staying sharper, this is a great product! I am now chopping a lot of hybrid rye and maize for anaerobic digesters so I am keen to finding what other products you sell, especially the wavy shearbar and processor rolls." - Alan Roberts
