Description

When your John Deere starts making that grinding noise from the rear end or you feel vibration coming up through the seat, it’s often these gears telling you they’ve had enough. The crown wheel and pinion in your differential handle all the power from your engine to the wheels, and they’re what give you the torque multiplication needed for heavy pulling and tough field conditions. This replacement gets your drivetrain running smooth and quiet again.

What You’re Getting

Precision-machined gears that transfer engine power efficiently to your wheels
Proper gear ratio for optimal torque multiplication during heavy pulls and field work
OEM-quality construction built to handle the stress of modern farming operations
Direct replacement that restores your differential to factory performance

Built for Real Farm Work

This crown wheel and pinion fits John Deere 6M and 6R series tractors—machines that handle everything from loader work and hay operations to precision row crop farming. Whether you’re running a mid-size utility tractor for hay work or a bigger machine for row crop farming, these are the same gears that transfer your engine’s power to the wheels for all that pulling, pushing, and hill climbing.

Made to Last

Farm equipment gears take a pounding, especially when you’re pulling heavy loads or working in tough conditions. This set uses the same metallurgy and heat treatment as the original equipment, so the gear teeth stay hard where they need to be while the gear body remains tough enough to handle shock loads without cracking.

Installation Notes

This is a precision job that requires proper setup of gear mesh patterns and bearing preloads. Most experienced mechanics plan on a full day for the job, and you’ll need clean gear oil for reassembly. If you’re hearing noise from the differential, don’t wait—worn gears can damage other expensive components.
