John Deere Part Numbers

John Deere provides a detailed, diagram-based parts catalog that shows exact part numbers for each component.

Steps

  1. Go to the John Deere Parts Catalog

    https://partscatalog.deere.com/

  2. Search by model, serial number, or equipment type

    Examples:

    • Tractor model (e.g. 4020, 5065E)

    • Engine model

    • PC (Parts Catalog) number

  3. Select the correct machine from the results.

  4. Open the relevant section or exploded diagram.

  5. Locate the part number listed next to the diagram reference number.

Notes

  • One diagram reference may list multiple part numbers depending on serial-number breaks.

  • Always match the part number to your exact model and serial range.

  • The part number shown is the official OEM John Deere part number.

Yanmar Part Numbers

Yanmar parts are found on the Yanmar official parts catalog or by requesting a pdf parts catalog for your machine or engine. To request a pdf catalog use the contact form or email parts@greenspringtractor.com with your complete model code or model number.

Steps

  1. Go to the Yanmar Parts Portal

    https://www.buyyanmar.com/parts

  2. Select the correct category:

    • Tractor

    • UTV

    • Industrial or Marine Engine

  3. Enter your model number to browse by category.

  4. Click search to show available diagrams.

  5. Click on the desired Diagram

  6. Search the Yanmar part number on our site

Notes

  • Yanmar part numbers are usually shown directly in the listing.

  • Some older or gray-market equipment may require dealer assistance.

  • If multiple versions exist, verify by engine or tractor model.

OEM vs Aftermarket Part Numbers

  • OEM part numbers come directly from the manufacturer (John Deere or Yanmar).

  • Aftermarket parts often reference the OEM number as a cross-reference.

  • When ordering, providing the OEM number is the most accurate method.

If you cannot find a part number or want confirmation:

  • Send us:

    • The part number you found, or

    • A screenshot of the diagram or listing, or

    • Your machine model and serial number
