Description
When you’re cutting hay or making silage, dull or damaged disc mower knives can turn a smooth day into a frustrating struggle. You’ll see ragged stubble, higher power draw from your tractor, and crops that don’t cure right because they’re being crushed instead of cleanly cut. This left-hand drum knife restores the sharp, precise cutting your mower was designed to deliver.
What You’re Getting
- High-quality KONDEX steel that holds a sharp edge longer and resists impact damage from rocks
- 7-degree twist design that provides the right cutting angle for clean stem separation
- Counter-clockwise rotation for proper operation on the left side of your mower
- Exact fit replacement with proper bolt hole sizing at 0.889 inches
- 4.3-inch length with the right thickness to balance cutting performance and durability
Built for Real Farm Work
This knife fits Case IH and New Holland disc mowers that use the rotating drum cutting system. Whether you’re cutting alfalfa, grass hay, or corn silage, these machines rely on sharp, properly twisted knives to slice through stems cleanly at high speeds. The 7-degree twist gives you the aggressive cutting action needed for thick-stemmed crops while still leaving a clean stubble.
Made to Last
KONDEX has been making cutting tools for decades, and they know what it takes to survive in the field. This knife is heat-treated to maintain its edge through rocks, dirt, and the constant impact of high-speed cutting. The steel formulation balances hardness for edge retention with toughness to resist chipping and breaking.
Installation Notes
This is a direct replacement that bolts right on with the RF925K bolt kit. When you’re replacing knives, it’s smart to do them in pairs to keep your cutting balanced. Check the drum for damage and clean off any grass buildup before installing the new knife.
