Description
When you’re out there cutting weeds or shredding stalks, there’s nothing more frustrating than losing a flail blade because the mounting hardware gave out. This square D-ring is what keeps your flail blades securely attached to the rotor shaft, letting them spin freely to cut through whatever you’re throwing at them. It’s a small part that does a big job—without it, your blades can’t do what they’re supposed to.
Key Features
- Square design provides more surface contact than round rings for better durability
- 9/16″ material thickness stands up to the constant impact and vibration
- Allows blades to pivot and flex around obstacles without breaking
- Precise dimensions ensure proper blade clearance and cutting action
- Direct replacement for factory hardware—no modifications needed
Built for Heavy-Duty Cutting
This D-ring works with the LK718 cup knife blade on Balzer, Fox Brady, Hiniker, Brillion, and Buffalo flail mowers. These are serious cutting machines used for everything from roadside mowing to chopping up crop residue after harvest. Whether you’re maintaining fence rows or preparing fields, this hardware keeps your blades working the way they should.
Made to Last
The 9/16″ thick material is built to handle the punishment that comes with flail mower work. Every time a blade hits a rock or chunk of wood, that impact gets transferred through the D-ring. This one’s made from quality steel that won’t crack or wear out after a few hours of tough cutting.
Installation Notes
This D-ring slides right onto your rotor shaft and holds the blade in place with a simple bolt-through design. It’s used with a 1/2″ x 1-3/4″ carriage bolt and locknut to secure everything together. Keep a few spares on hand—it’s always easier to replace worn hardware during scheduled maintenance than when you’re broken down in the field.
