When your implement hub assembly is wobbling or making noise, that 1-3/4 inch spindle is usually the culprit. You know the sound—that grinding or clicking from the wheel that means expensive downtime if you don’t fix it soon. This replacement spindle gets your disc, cultivator, or other implement wheel spinning true again, so you can get back to the important work.
What You’re Getting
- Precise 1-3/4 inch diameter shaft fits 30-6 hub assemblies perfectly
- 9.9-inch length provides the right bearing spacing for smooth operation
- Made in the USA from quality steel that handles field conditions
- Direct replacement for worn or damaged spindles in agricultural equipment
- Works with standard spindle nut 912593 and washer 913616 (sold separately)
Built for Real Farm Work
This spindle fits the popular 30-6 hub series found on disc harrows, cultivators, planters, and other implements that need reliable wheel assemblies. These 3,000-pound capacity hubs are workhorses on medium-duty equipment—tough enough for rocky fields but not so heavy they bog down your tractor. Whether you’re discing stubble or cultivating beans, this spindle handles the side loads and impacts that come with implement work.
Made to Last
Farm spindles take a beating from rocks, stumps, and the constant vibration of field work. This one’s manufactured to handle those conditions with proper heat treatment and machined bearing surfaces that won’t wear prematurely. The steel construction resists bending from impacts, while the precision dimensions ensure your bearings get the support they need for long life.
Good to Know
You’ll need the spindle nut and washer to complete the job—they don’t come with the spindle but are available separately. If you’re replacing one spindle due to wear, it’s smart to check the other wheels while you’ve got the tools out. A little bearing grease on the threads makes installation easier and prevents future corrosion.
