Description
When your disc mower starts leaving uncut strips or the stubble looks ragged instead of cleanly sliced, it’s time to check your drum knives. Dull or damaged blades don’t just hurt cutting quality—they make your tractor work harder and can leave crops that don’t cure properly. This right-hand drum knife gets your mower back to making the clean cuts that help hay dry evenly and livestock stay healthy.
What You’re Getting
- Precision-engineered 7-degree twist that creates the optimal cutting angle for clean slicing action
- Right-hand rotation design that spins clockwise to match your mower’s drum configuration
- KONDEX quality construction that holds a sharp edge longer than cheap alternatives
- Direct bolt-on replacement that uses your existing hardware—no modifications needed
- Heavy-duty 4.0mm thickness that resists chipping from rocks and debris in the field
Built for Real Farm Work
This knife fits Case IH and New Holland disc mowers that need the right-hand rotation blade. Whether you’re cutting first-crop alfalfa, prairie grass, or roadside vegetation, the 7-degree twist helps the blade slice through stems cleanly instead of tearing them. The clockwise rotation works with your mower’s drum design to create the airflow that lifts grass into the cutting zone.
Made to Last
KONDEX builds these knives to handle the punishment that comes with real farm work. The steel holds its edge through thousands of acres, and the 7-degree twist is formed during manufacturing—not bent afterward—so it won’t lose its shape over time. Even when you hit the occasional rock or fence post, this blade bounces back instead of breaking.
Installation Notes
This knife bolts right into place using the RF925K bolt kit made for Case IH and New Holland mowers. When installing, make sure the twist faces the right direction—the leading edge should angle down slightly as the drum rotates. It’s worth replacing knives in pairs to keep your cutting balanced and reduce vibration.
