Description

When your three-point hitch isn’t lifting evenly or you’re hearing that telltale grinding from the back of your tractor, chances are good your lift arm rock shaft needs attention. This is the heart of your hydraulic lift system—the shaft that transfers power from your hydraulic cylinders to the lift arms that raise and lower your implements. When it starts wearing out, you’ll notice implements hanging crooked or taking forever to lift.

What You’re Getting

Complete kit with all the parts you need to rebuild your lift arm rock shaft system
Properly machined components that fit like the originals and handle the same loads
Quality materials that stand up to the constant pressure and movement of three-point operation
Everything included so you’re not making multiple trips to the parts counter

Built for Real Farm Work

This kit is designed for John Deere 6000 series tractors including the 6100, 6200, 6300, 6400, 6500, and 6600 models up to serial number 187951. These are the workhorses you see on farms everywhere—big enough to pull serious implements but still maneuverable enough for loader work around the barn. Whether you’re running a disc, planter, or heavy finishing mower, this rock shaft takes all the stress and keeps your implements level.

Made to Last

Rock shafts take a beating from constant hydraulic pressure and the weight of heavy implements. This kit uses quality steel components that are heat-treated and precision-machined to handle those loads. The parts are built to OEM specifications, so you’re getting the same durability that came with your tractor from the factory.

Good to Know

This is a more involved repair that’s best tackled when you can get the tractor in a shop with good lighting and room to work. You’ll need to drain the hydraulic system and remove the lift arms to access the rock shaft assembly. If you’re not comfortable with hydraulic system work, this is a good job for your local mechanic who knows these tractors.
