Description

When you’re mowing hay or cutting cover crops, nothing’s more frustrating than dull or damaged drum knives that tear instead of cut. This Kondex replacement knife gets you back to making clean cuts that cure properly and don’t leave ragged edges in your field. These knives are built tough to handle the bumps, rocks, and debris that come with real farm work.

What You’re Getting

9-degree twist design that slices cleanly through thick stems and grasses
Clockwise rotation for the right side of your disc mower drum
4.75-inch length with precise 0.889-inch bolt hole for a secure fit
Heat-treated construction that stays sharp longer in tough cutting conditions
Direct replacement that bolts right on without modifications or adapters

Built for Real Farm Work

This knife fits a wide range of disc mowers from Bush Hog, Rhino, New Idea, and Agco Hesston brands. Whether you’re cutting alfalfa, grass hay, or cleaning up ditches and fencerows, this is the same quality knife that came on your mower from the factory.

Made to Last

Kondex knives are forged from high-carbon steel and heat-treated to handle the punishment of field work. The 9-degree twist angle gives you an aggressive cutting action that slices instead of tears, which means better hay quality and less wear on your mower’s drive components.

Installation Notes

This is a right-hand knife, so it goes on the clockwise side of your drum. Use the RF527K bolt kit for proper installation on Bush Hog, New Idea, and Agco equipment. A quick tip: replace knives in pairs to keep your cutting drum balanced and running smooth.
