Description

When your John Deere 6M or 6R starts making those worrying whining or clunking noises from the front end, especially when turning or under heavy load, you’re likely dealing with worn planetary gears. That ring gear is the backbone of your front final drive system, and when it starts to go, every turn becomes a reminder that you need to address it before minor wear becomes major damage.

What You’re Getting

Precision-machined ring gear designed to mesh perfectly with your planetary gear system
Heavy-duty construction that handles the torque demands of modern John Deere tractors
Direct OEM replacement that restores proper gear mesh and quiet operation
Quality materials built to withstand the shock loads of loader work and field operations

Built for Real Farm Work

This planetary ring gear fits John Deere 6M series tractors including the 6105M, 6115M, 6125M, and 6130M models, plus 6R series tractors like the 6105R, 6115R, 6110R, 6120R, and 6R110. Whether you’re running a smaller 6M with a loader for daily chores or pushing a big 6R through heavy tillage work, this gear handles the massive torque loads that get transferred through your final drive every time you engage four-wheel drive or work the loader.

Made to Last

The precision-manufactured gears restore proper mesh patterns and clearances, bringing back smooth, quiet operation. This gear uses heavy-duty materials that can handle everything from the shock of hitting fieldstone to the constant strain of loader work, with precision-cut teeth that mesh smoothly to reduce wear and heat buildup.

Installation Notes

Replacing a planetary ring gear isn’t a quick roadside fix – plan on spending the better part of a day on this job since you’ll need to drain the front axle oil and likely remove the wheel and hub assembly to access the planetary unit, and here’s a tip from experience: mark everything before disassembly with a paint pen or marker. Those planetary carriers can go back together multiple ways, but only one is correct, so clean all mating surfaces thoroughly, use new gaskets, and don’t skimp on quality gear oil when you refill.
