This page covers the John Deere X300 model. It is separate from the broader X300 Series hub, which links to other models in the family.
Identify your X300 configuration
Record the tractor PIN, engine model and serial number, and mower-deck model. The deck and engine have their own parts and service references. Match the publication to the X300 and the serial range shown; do not apply a specification from another X300-family model by name alone.
Check fitment before buying parts or attachments
- Use the deck number for blades, belts, and mower components.
- Use the engine label for engine parts and maintenance instructions.
- Confirm attachment mounting and model-year or serial limits in the Deere document.
- Ask a dealer to resolve a missing plate or an assembly that differs from the parts illustration.
Search John Deere technical publications for manuals and use the official parts catalog for diagrams and applicability notes. For navigation to the family and related model pages, return to the X300 Series guide.
