These gears are the workhorses that transfer all your engine’s power to the wheels, handling every ounce of torque you need for heavy pulls and tough field conditions. This replacement set gets your drivetrain running smooth and quiet again so you can focus on the work ahead.

Built for Real Farm Work
This gear set fits John Deere’s most popular mid-size tractors from the reliable 6020 series utility machines through the modern 6M and 6R models. Whether you’re running loader work with a 6320, pulling tillage equipment with a 6630, or handling precision farming operations with a 6140M, these are the same gears that came from the factory.
Made to Last
Farm equipment gears take a real pounding, especially when you’re pulling heavy loads or working in tough conditions. This set is built with the same quality materials and heat treatment as the original parts. The gear teeth are precision-machined to maintain proper spacing and contact, which means less wear and longer life.
Installation Notes
Crown wheel and pinion replacement requires dropping the differential and proper gear setup with shimming for correct backlash. If you’re not comfortable with differential work, this is a job for your mechanic. Check your differential oil level regularly after installation—proper lubrication is critical for gear life.
