Good To Know

Q: Is this bolt compatible with all John Deere Ztrak models? A: It fits most Ztrak and Eztrak series, but verify serial number range for your specific model to ensure proper length and thread pitch.

Q: Can I reuse the old lock washer or nut? A: It is recommended to use new hardware for a secure fit; the bolt alone does not include fasteners, so check your existing setup.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
