Description

When you’re hooking up implements and notice the PTO connection feels loose or won’t engage properly, it’s often a worn coupler that’s causing the problem. This fine-splined coupler with 21 splines creates a solid connection between your tractor’s PTO and your implements, eliminating the play that causes vibration and premature wear. If you’ve been dealing with rough PTO operation or hearing grinding noises during engagement, this replacement coupler gets power flowing smoothly again.

What You’re Getting

Precision 21-spline configuration for tight, secure fit with no slop
Fine spline design distributes torque evenly across more contact points
Heavy-duty construction that handles full engine power without twisting
Direct OEM replacement – no modifications needed for proper fit

Built for Real Farm Work

This coupler works with a wide range of Massey Ferguson tractors from the smaller 100 series utility models through the heavier 300 series machines, plus John Deere tractors from compact utility models up to the big 9000 series four-wheel drives. Whether you’re running a rotary cutter, hay baler, spreader, or tillage equipment, this coupler handles the power transmission demands these implements require.

Made to Last

PTO couplers take serious abuse from constant engagement cycles, shock loads, and the torque spikes that come with heavy implement work. This coupler is built from quality steel with proper heat treatment to resist wear and maintain tight tolerances. The fine spline design spreads loads across more contact area, reducing stress concentration that causes premature failure.

Good to Know

Installation is straightforward – slide off the old coupler and press on the new one. Clean the shaft thoroughly before installation and check that the coupler slides on smoothly without binding. A thin coat of anti-seize on the splines helps with future removal and prevents corrosion. Always make sure the coupler is fully seated before operating.
