Description

When you’re in the middle of hay season and your baler suddenly stops working, the last thing you want is a blown flywheel because a shear bolt didn’t do its job. These flywheel shear bolts are your baler’s first line of defense—they’re designed to break before expensive drive components do when rocks, metal, or thick material jams things up. Think of them as the fuse in your electrical panel, but for your baler’s drivetrain.

What You’re Getting

10 complete bolt and nut sets so you’re ready for the whole season
5/16″-18 x 2-1/4″ hex head bolts with matching lock nuts, all zinc plated for corrosion resistance
Exact specifications that match your baler’s protection needs—not too strong, not too weak
Quality construction that breaks clean when overloaded, protecting your flywheel and drive system

Built for Real Farm Work

This kit fits John Deere balers including models 214, 225, 346, 347, 348, 466, 467, and 468. These are the workhorses you see making hay in fields everywhere—from small square balers on hobby farms to the bigger machines handling commercial hay operations. Whether you’re baling grass hay, alfalfa, or straw, these bolts give you the protection you need.

Made to Last

The zinc plating keeps these bolts from rusting in storage, but don’t expect them to last forever once installed—that’s the whole point. They’re engineered to sacrifice themselves when your baler hits something it shouldn’t, saving you from a much more expensive repair bill on the flywheel or drive components.

Good to Know

Keep a few spares in your toolbox because you’ll likely go through several during hay season, especially in rocky fields. When a shear bolt breaks, replace it immediately and check what caused the jam before starting back up. It’s also smart to inspect the flywheel area while you’ve got it apart—better to catch wear now than have it fail during your busiest week.
