Description
When your disc mower starts leaving ragged stubble or pulling more power than usual, it’s time to look at those cutting blades. Dull or damaged blades crush stems instead of cleanly slicing them, which hurts crop quality and makes your tractor work harder. This left-hand drum knife gets your Kuhn or New Holland disc mower back to making clean, precise cuts that let your hay cure properly.
What You’re Getting
- 11-degree twist angle designed for optimal cutting performance and debris flow
- KONDEX quality construction that holds a sharp edge longer than cheaper alternatives
- Precise 0.650-inch bolt hole for secure mounting with no wobble or play
- Counter-clockwise rotation specifically engineered for left-hand disc positions
- 3.6-inch length provides the right balance of cutting surface and clearance
Built for Real Farm Work
This knife fits Kuhn and New Holland disc mowers used for cutting hay, silage crops, and pasture maintenance. Whether you’re making first cutting alfalfa or chopping corn stalks in the fall, this blade handles the tough cutting conditions that come with real farm work. The twisted design helps move cut material away from the disc for cleaner operation.
Made to Last
KONDEX builds these knives from high-carbon steel that’s heat-treated for the right balance of hardness and toughness. The 0.12-inch thickness gives you durability without being so thick it dulls quickly, and the precision manufacturing means each blade cuts consistently across your entire swath width.
Installation Notes
This is a direct replacement that bolts right in place of your worn blade. Use bolt kit RF56152 for Kuhn and New Holland applications. A quick tip: when replacing blades, check all the others on that disc—if one’s worn, the rest probably aren’t far behind. Having a matched set keeps your cutting even.
