Description
When your disc mower starts leaving uncut grass or makes ragged cuts, it’s usually time for new knives. These twisted drum knives are what keep your mower cutting clean through thick hay and grass all season long. A sharp, properly angled knife makes the difference between hay that dries quickly and hay that sits in the field too long.
What You’re Getting
- Left-hand rotation design with an 11-degree twist for aggressive cutting action
- KONDEX construction that’s built to handle rocks, dirt, and tough cutting conditions
- Precise 0.65-inch bolt hole that fits snugly with standard hardware
- 3.6-inch length provides the right balance of cutting edge and durability
- Direct replacement for OEM knives—no modifications needed
Built for Real Farm Work
This knife fits Kuhn and New Holland disc mowers, the workhorses you’ll find cutting hay fields from small dairies to large cattle operations. These machines need to handle everything from tender alfalfa to tough prairie grass, and they depend on sharp, well-designed knives to get the job done.
Made to Last
The KONDEX brand knows what it takes to survive in hay fields. These knives are forged to hold their edge longer and resist the kind of abuse that comes from hitting fence rows, rocks, and whatever else is hiding in the grass.
Good to Know
Don’t forget to pick up the matching bolt kit—it’s listed in the specs as RF56152 for your Kuhn or New Holland setup. When you’re replacing knives, it’s smart to do them in pairs or complete sets to keep your cut even across the full width.
