Description

When you lose four-wheel drive in the middle of a tough pull, you’ll know it right away—and it’s usually this coupling that’s given up the fight. The 4WD coupling is the critical link that transfers power to your front axle, and when it fails, you lose the traction needed for demanding field conditions. This bolt-on flange coupling with 19 teeth is built to restore full power transfer and get your tractor pulling with all four wheels again.

What You’re Getting

Heavy-duty materials specifically chosen for the high-torque demands of 4WD applications to handle the stress of real farm work
Bolt-on flange design that provides a solid, secure connection without the play that causes premature wear
19-tooth spline configuration that meshes precisely with your Case MX or McCormick transmission
Direct replacement design that fits without modifications or adapters

Built for Real Farm Work

This coupling is engineered for Case IH Maxxum MX series tractors and McCormick MTX, MC, and XTX series machines—tractors that earn their keep in demanding applications from loader work to heavy field operations. Whether you’re pulling through muddy ground, working steep terrain, or pushing snow, this coupling keeps your front wheels engaged when traction matters most.

Made to Last

This coupling uses heavy-duty materials specifically chosen for the high-torque demands of 4WD applications, with heat treatment that provides the hardness needed to resist wear while maintaining toughness to prevent brittle failure under shock loads. It’s built to handle the constant flexing and stress that comes with serious agricultural work.

Installation Notes

Installation requires proper alignment to prevent binding, and it’s important to clean all splines thoroughly before assembly. Apply a light coat of grease to the splines during installation and make sure everything engages fully—partial engagement causes rapid failure. Always test your 4WD operation in both directions after installation to ensure everything’s working properly.
