Description

When you’re out cutting hay and notice your disc mower blades wobbling or making noise, it’s usually those blade nuts working loose. A loose blade throws off the whole cutting action—you get uneven stubble, missed grass, and vibration that’ll shake your teeth loose. This replacement blade nut keeps everything tight and balanced so your mower cuts clean from dawn to dusk.

What You’re Getting

Secure threading that locks blades in proper position for even cutting
Heavy-duty construction that handles the constant spinning and impact
Direct replacement for worn or damaged nuts—no modifications needed
Precision machining that ensures proper blade balance and smooth operation

Built for Real Farm Work

This nut fits disc mowers across New Holland, AGCO, and Case IH hay equipment lines. Whether you’re running a self-propelled windrower or a pull-type disc mower behind your tractor, these are the same nuts that came on your machine from the factory. Perfect for dairy operations, beef producers, and anyone making quality hay.

Made to Last

Disc mower blades spin thousands of RPMs and hit rocks, stumps, and other surprises hiding in the grass. These nuts are built from high-strength steel that won’t strip, crack, or work loose under those demanding conditions. The precise threads and hardened construction mean they’ll hold your blades secure season after season.

Installation Notes

Always replace blade nuts in matched sets to maintain proper balance—mixing old and new can cause vibration. Use a torque wrench to tighten to manufacturer specs, and check them after the first few hours of operation. If you’re replacing blades too, this is a good time to inspect the disc for cracks or wear.
