Description

When you’re cutting hay or running a mowing operation, the last thing you want is your disc mower developing wobble or vibration that affects your cut quality. That’s often a sign your shear hub driver system needs attention. This replacement kit contains all the critical components to rebuild your disc hub assembly, getting you back to making clean, uniform cuts across every swath.

Key Features

Complete rebuild kit eliminates the guesswork of ordering individual components
Engineered to handle the high rotational speeds and shock loads of disc mowing operations
Precision-balanced components prevent vibration that can damage the entire cutterbar
Heavy-duty construction stands up to rocks, fence posts, and other field hazards

Built for Real Farm Work

This kit fits John Deere windrower models that rely on disc-type cutting systems for hay operations, pasture topping, and roadside maintenance. Whether you’re making first cutting alfalfa where every stem matters or cleaning up fence rows, these are the machines that handle the volume work where downtime costs money.

Made to Last

Disc cutters take tremendous abuse from spinning at thousands of RPM while hitting everything from rocks to stumps. This rebuild kit uses quality materials that resist impact damage and maintain balance through extended use. The shear protection built into the design prevents costly damage to your gearbox when you do hit something immovable.

Installation Notes

Plan on having the cutterbar off the machine for this repair – it’s not a roadside fix. Clean all old grease and debris from the hub housing before assembly, and use proper torque specs on all fasteners. A quick tip: mark the disc blade position before disassembly so you can maintain the same balance when reassembling.
