This page is about the John Deere X320 model, not every tractor in the X300 family. For a family-level overview and links to other models, see the John Deere X300 Series guide.
Identify the X320 configuration
Record the tractor PIN, engine model and serial number, and installed mower-deck identification. Choose a Deere publication that lists the X320 and includes your serial range. The deck number is important: blades, belts, and deck procedures should be matched to that assembly rather than inferred from the tractor name.
Before ordering a part or attachment
- Compare the PIN with the parts diagram’s applicability notes.
- Use the engine label for engine service parts.
- Check an attachment’s mounting method and stated model-year or serial limits.
- Do not assume that a part advertised for another X300-family model fits the X320.
Start with John Deere technical publications and verify the assembly in the official Deere parts catalog. Keep the model and serial details with the machine’s maintenance records.
