Description

When you’re hearing grinding or whining noises from your final drive, or feeling that telltale shudder when turning under load, it’s time to pay attention. Your planetary gears are the workhorses inside your John Deere’s final drive, handling every ounce of power from the engine to put torque where it belongs—at the wheels. When these gears start wearing, they don’t just quit gradually; they can take out expensive ring gears and bearings with them.

What You’re Getting

Precision-manufactured gear with exact specifications to restore proper mesh and clearances
Heat-treated steel construction that handles the massive torque loads in your final drive
Direct replacement design that fits perfectly in your existing planetary carrier
Quality materials that resist wear under the constant stress of field operations

Built for Real Farm Work

This planetary gear fits the popular John Deere 6M and 6R series tractors that handle everything from loader work to heavy draft applications. Whether you’re running a 6120M with a grapple bucket, pulling a heavy cultivator with your 6130R, or climbing steep hills with implements, these gears multiply the torque from your transmission to give you the pulling power at the wheels.

Made to Last

Farm planetary gears see tremendous stress every time you push silage, pull through muddy fields, or climb hills with heavy loads. This gear is built with proper heat treatment and quality steel to handle those shock loads and constant torque cycling that comes with real farm work. When planetary gears fail, metal particles contaminate the oil and accelerate wear throughout the final drive.

Good to Know

Planetary gear replacement requires draining the final drive and careful disassembly of the carrier assembly. This is skilled work that takes most experienced techs 3-5 hours per side. Absolute cleanliness is essential—any debris will quickly damage new gears. While you’re in there, inspect the sun gear, ring gear, and all bearings for wear. Use only the specified gear oil and proper fill levels when reassembling.
