Description

When your three-point hitch starts acting up—implements drifting down, uneven lifting, or that side-to-side wobble that makes precision work impossible—you’re usually looking at worn rock shaft components. This 31-spline rock shaft kit brings everything back to factory-tight specs, giving you the precise three-point control you need for serious implement work.

What You’re Getting

Complete 31-spline rebuild kit with all the parts you need in one box
Category 2 specifications with precise 20mm leveling box pin hole for proper fit
31-spline design distributes loads across more contact surfaces for superior strength
Includes bolt, seal, washer, bushing, and shaft—everything works together as a system
Wide compatibility across standard, L, S, SP, and SE model variants

Built for Real Farm Work

This kit fits the workhorses of many operations—John Deere 6000 series tractors from the 6100 through 6600, the versatile 6005 series including 6205, 6405, and 6605 models, plus the entire 6010 series lineup. These tractors handle everything from loader work to heavy tillage, and when you’re pulling Category 2 implements like disc harrows, cultivators, or rotary cutters, precision matters.

Made to Last

The 31-spline design offers superior strength compared to lesser spline counts, spreading the load across more contact surfaces where it matters most. Precision-machined components fit together properly the first time, and the 20mm leveling box pin hole is accurately sized to eliminate slop while still allowing smooth adjustment.

Good to Know

Rock shaft work requires attention to detail for lasting results. Start by verifying your tractor uses the 31-spline design—not all models in these series are identical. Support your implements safely during teardown and document positions before you start. Clean everything thoroughly because contamination ruins hydraulic seals fast. Take your time with alignment during reassembly—the shaft needs to rotate smoothly without binding for proper operation.
