Description

When your tractor starts making grinding noises during PTO engagement or you’re getting rough power transfer to implements, it’s often this internal gear causing the trouble. PTO problems that cut out halfway through baling or refuse to engage when you’ve got implements waiting can shut down your whole operation. The countershaft gear is what takes power from your engine and transfers it through the PTO transmission to the output shaft that drives your equipment—when it wears out, everything stops working smoothly.

Key Features

Precision-cut gear teeth mesh properly with your PTO transmission components for smooth power transfer
Heat-treated steel construction handles the constant torque loads and shock from implement engagement
Exact-fit replacement that restores proper gear timing and eliminates grinding noises
Engineered for the demanding duty cycles of modern farming operations

Built for Real Farm Work

This gear fits John Deere 6R series tractors (6105R-6250R) that are the workhorses of modern farming operations. Whether you’re running a 6420 with a round baler, operating a rotary cutter with a 6130R, or powering a mixer wagon with a 6155M, this gear handles the daily cycling and heavy loads that come with serious farm work. These tractors power everything from hay operations to tillage work where reliable PTO performance is critical.

Made to Last

Farm PTO systems work harder than most people realize, with constant torque loads, shock absorption from implement engagement, and demanding duty cycles. This gear is precision-machined to exact specifications that ensure smooth power transfer without vibration and binding. The steel construction resists the wear that comes from thousands of operating hours and the heat generated inside transmission housings.

Good to Know

This isn’t a weekend project—replacing internal PTO gears requires splitting the transmission and proper tools for installation. While you’ve got things apart, it’s smart to inspect other PTO components and replace any seals showing wear. Clean all surfaces thoroughly during reassembly and use the specified torque values to prevent future problems.
