Nothing’s more frustrating than dealing with a loose transport wheel when you’re trying to get across town or down a busy highway.

- Secure fit that keeps your transport wheel bearings properly tensioned

Built for Real Farm Work
This nut is specifically designed for Case IH 480-490 disc harrows and works with the corresponding transport spindle assembly. These harrows spend a lot of time on the road between fields, and this nut handles the constant vibration and stress that comes with moving heavy equipment at transport speeds.
Made to Last
Transport components take a beating from road vibration, dust, and weather. This nut is built with the strength to handle repeated tightening and loosening while maintaining its grip on the spindle threads. The hex design gives you a solid grip when it’s time for maintenance or bearing service.
Good to Know
Always check spindle nut tightness before hitting the road – a loose transport wheel can cause serious problems. When installing, tighten to proper torque spec and use a thread locker if recommended by your manual. It’s a good idea to inspect the spindle threads for wear while you’ve got the nut off.
