Disc Mower Drum Knife for Kuhn and New Holland Disc Mowers – Left Hand

Description

When your disc mower blades start leaving ragged stubble or you’re seeing uncut strips in your field, it’s time for fresh blades. A dull or damaged knife doesn’t just cut poorly—it crushes stems instead of slicing them clean, which means your hay won’t cure right and you’ll be fighting increased power draw from your tractor. This left-hand drum knife from KONDEX gets you back to making clean, precise cuts.

What You’re Getting

• 7-degree twist design that creates the perfect cutting angle for clean slicing action
• Counter-clockwise rotation pattern that works with your mower’s disc configuration
• KONDEX quality steel that holds a sharp edge longer and resists chipping from rocks
• Precise 3.7-inch length and balanced weight distribution for smooth operation
• 0.650-inch bolt hole that matches your existing hardware perfectly

Built for Real Hay Work

This knife is made for the demanding world of disc mowing where you’re cutting everything from delicate alfalfa to tough grass hay. Whether you’re running a Kuhn GMD series mower or a New Holland disc mower, this blade delivers the factory-spec performance your machine was designed for. The 7-degree twist angle gives you the aggressive cutting action needed for thick stands while still providing a clean cut that promotes proper curing.

Made to Last

KONDEX has been making cutting tools for farm equipment for decades, and they understand what it takes to survive in the field. This blade is heat-treated for durability and designed to handle the constant impacts from stones, dirt, and debris that come with mowing real-world fields. The balanced design reduces vibration and wear on your disc bearings.

Good to Know

This is the left-hand knife, so make sure you’re ordering the correct rotation for your disc position. If you’re replacing multiple blades, it’s worth doing them all at once—mixing new sharp blades with worn ones can cause vibration and uneven cutting. Don’t forget to check your bolt and nut condition while you’re in there.
