FAQ

What does this PTO clutch replace?

This aftermarket clutch replaces John Deere AUC11007, TCA22879, TCA21166, and TCA20605. It also cross-references Warner 5228-38, Warner 5228-55, and Xtreme X0807.

Does this clutch fit a John Deere Z925A?

It fits select Z925A and Z925A EFI applications using the AUC11007 clutch family. It does not fit every Z925A. Late-serial machines with a 54-inch Mulch On Demand deck can use the separate TCA21167 clutch path.

Does this clutch fit a John Deere Z920A?

It fits select Z920A 60-inch deck applications with serial number 020001 and higher when the original clutch number matches this listing. Earlier machines and other deck configurations can use different clutch families.

Are AUC11007 and TCA21167 interchangeable?

No. They are different clutch paths used on different deck and production configurations. Match the original clutch number, pulley, connector, and anti-rotation setup.

What should I check before ordering?

Confirm the original clutch number, mower serial number, deck configuration, 1-1/8-inch crankshaft bore, pulley diameter and offset, electrical connector, belt alignment, and anti-rotation position.
