Description

When your PTO system starts grinding, making noise, or won’t transfer power smoothly to your implements, the problem might be deeper than just a worn shaft. This PTO output shaft gear is the critical internal component that takes power from your transmission and transfers it to the output shaft that runs your implements. If this gear gets worn or damaged, you’re not just dealing with poor performance—you’re looking at potential damage to expensive implements and costly downtime during critical work seasons.

What You’re Getting

Precision-machined gear teeth that mesh properly with your PTO system for smooth power transfer
Heat-treated steel construction that handles full engine torque without stripping or wearing prematurely
Exact OEM specifications that ensure proper fit and function in your 7R series transmission
Quality manufacturing that eliminates the vibration and noise you get from worn internal components

Built for Heavy-Duty Operation

Your John Deere 7R series tractor is designed for serious farming—pulling heavy implements, powering demanding equipment, and handling the kind of work that puts maximum stress on every component. This gear works inside your PTO system where temperatures run high and loads are constant, transferring hundreds of horsepower from your engine to implements like large rotary cutters, heavy-duty balers, and high-capacity manure spreaders.

Made to Last

Farm work doesn’t give PTO components any breaks, and internal gears face some of the toughest conditions in your tractor. This gear is manufactured from high-grade steel and heat-treated to resist wear even under constant load cycling. The precise tooth geometry ensures proper meshing that prevents the accelerated wear you get when tolerances are off.

Good to Know

Replacing internal PTO gears is a serious job that typically requires splitting the transmission case—this isn’t a quick field repair. If you’re hearing grinding noises from your PTO, don’t keep running it. Continued operation with worn gears can destroy other expensive components inside your transmission. Consider having this work done during scheduled maintenance to avoid emergency repairs during busy seasons.
