Description
When your disc harrow starts wobbling or the gang won’t turn freely, there’s a good chance the axle is worn out. This replacement axle fits John Deere disc harrow models 210, 215, 220, 230, 235, and 630—the workhorses that have been breaking ground and working crop residue for decades. A bent or worn axle makes the whole gang assembly run rough and can damage your expensive disc blades.
What You’re Getting
- Heavy-duty 1-1/8 inch square steel construction that handles the torque and stress of field work
- Full 77-11/16 inch length with 3-1/2 inches of threaded end for secure mounting
- Precision-machined square profile that fits disc blades and spacers without wobble
- Direct replacement for original part A20616—no modifications needed
Built for Real Farm Work
These John Deere disc harrows are commonly used on farms for breaking up crop residue, preparing seedbeds, and general tillage work. Whether you’re working corn stubble in the fall or prepping ground for spring planting, this axle needs to handle thousands of blade rotations while dealing with rocks, roots, and uneven ground.
Made to Last
Farm equipment axles take a beating from constant rotation under load, and cheap replacements just don’t hold up. This axle is built from quality steel that resists bending and wear, so you’re not replacing it again next season. The square design distributes stress evenly across the shaft.
Good to Know
You’ll need the matching nut (part 120-84018) with 1-1/8-7 thread to secure this axle properly. Before installing, check your bearing housings for wear—a worn bearing will eat up a new axle fast. It’s also a good time to inspect your disc blades and spacers while you’ve got everything apart.
