Rock Shaft Rebuild Kit for John Deere 6020-6620 Series Three-Point Hitch

Description

There’s nothing more frustrating than trying to maintain level implements when your three-point hitch has excessive play or won’t lift evenly. If you’ve noticed your cultivator or rotary cutter drifting to one side or your hitch arms dropping under load, worn rock shaft components are likely the culprit. This complete rebuild kit brings back the precise control your tractor had when it was new.

What You’re Getting

• Complete rock shaft assembly with all bushings, seals, and hardware needed for the job
• Heavy-duty shaft machined from high-strength steel to handle constant load reversals
• Quality bushings that maintain proper clearances while handling side loads from heavy implements
• New seals prevent hydraulic leaks that rob lifting power and contaminate the environment
• Everything engineered to restore your hitch to factory specifications and performance

Built for Real Farm Work

Your John Deere’s three-point hitch is what connects you to every rear implement—from your cultivator and disc to your rotary cutter and manure spreader. When the rock shaft wears out, you lose that precise control that makes field work efficient. This kit fits the entire 6020 through 6620 series, including SE models, plus the 6005 series tractors that handle everything from specialty crop work to heavy tillage operations.

Made to Last

Farm work doesn’t get easier on equipment, and rock shaft components take a beating from constant lifting cycles and side loads from implements. The components in this kit are built to handle the punishment, with precision-machined surfaces and materials chosen for their ability to resist wear from hydraulic pressure changes and implement weight.

Good to Know

Rock shaft rebuilding is one of those jobs that pays big dividends in tractor performance. Take photos before disassembly to remember how everything goes back together, and clean the housing area thoroughly before you start. When installing new bushings, press them in carefully to proper depth—rushed installation leads to premature wear. The shaft should rotate freely without excessive play when you’re done. This is also the perfect time to service your lift cylinders and replace any worn pins throughout the three-point system.
