Title: Navigating the SDF Parts Catalogue: A Farmer’s Guide to Finding the Right Fit Published: April 11, 2026 Category: Maintenance & Repair

If you own a Same, Deutz-Fahr, Lamborghini, Hürlimann, or Grégoire tractor, you are part of the SDF family. These machines are known for their robust engineering and German-Italian efficiency. But when a hydraulic hose bursts in the middle of seeding or a gearbox seal starts weeping, the quality of your repair depends entirely on one thing: finding the exact part number.

Enter the SDF Parts Catalogue. It is your digital lifeline. But if you have ever opened it for the first time, you know it can feel like reading a blueprint for a spaceship.

Let’s break down how to use this tool effectively, and why you should avoid the "universal fit" gamble.

Tactic 3: NOS (New Old Stock) Search Engines

Take the OEM SDF number (e.g., 0.012.3456.7) and paste it into:

  • TractorHouse Parts
  • Salvage Yards' databases (Worthington Ag Parts)
  • eBay Motors (many dealers liquidate obsolete stock here)

Should you buy OEM or Aftermarket?

The SDF catalogue is an OEM tool (Original Equipment Manufacturer). It will only show you SDF-branded or licensed parts.

  • Use the catalogue for: Hydraulic seals, electronic sensors, injection pump parts, and body panels. These must fit perfectly.
  • Cross-reference for: Oil filters, fan belts, and batteries. Once you have the SDF number, you can usually cross it to a Mann, Bosch, or Donaldson equivalent at 50% of the cost.

3. Fuel Injectors & Pump Elements

  • Section: Group 11 - "Fuel System"
  • Look for: Bosch or Denso part numbers cross-listed. You may need a calibration code.
