How to Find Tractor Parts Online: Search Techniques, AI Tools, and Salvage Yard Directory
The part number is rubbed off. The dealer says discontinued. The salvage yard hung up. Every farmer and mechanic has been there. This guide covers the techniques we actually use to source NOS and used agricultural parts — including AI image search, eBay search strategies most people don't know, cross-reference tools that work, and a salvage yard directory with phone numbers.
Start With the OEM Part Number
Everything depends on getting the factory part number. Once you have it, every other source — eBay, cross-reference databases, salvage yards — becomes searchable. Without it, you're guessing.
John Deere Parts Catalog — Enter your model or equipment PIN. Shows exploded diagrams with part numbers for every assembly. This is step one for any John Deere repair. The catalog also lists available service publications for each model.
Case IH / New Holland Parts Catalog — Same underlying CNH system covers both brands. Search by model, PIN, or engine serial number.
Kubota Parts Lookup — Select series and model to see parts diagrams. Simpler than Deere's system but covers the Kubota lineup.
Tip: If you can't find your model in the online catalog, call the dealer parts counter. They have access to legacy catalogs that aren't online, especially for pre-2000s equipment. Ask them to read you the part number — most will do it without requiring you to buy from them.
Can't Read the Part Number? Use AI Image Search
When a part number is stamped into cast iron or painted over, you have options beyond squinting. For a full guide to using AI photo tools for parts identification — including ChatGPT, Google Lens, Plantix for weeds, and livestock condition identification — see our AI Parts Identification Guide.
Google Lens — Open the Google app on your phone, tap the camera icon, and point it at the part. Lens matches the shape against millions of product images. It works surprisingly well for bearings, filters, sensors, and brackets — parts with distinctive shapes. If the part has a logo or partial text, Lens can OCR it and search that text.
Case IH Visual Parts Search — Case IH and New Holland launched an AI visual search tool on mycnhstore.com. Take a photo of the part with your phone, upload it, and the system matches it against the CNH parts database. Works for current and recent Case IH / New Holland equipment.
Partium — Industrial AI parts identification. Upload a photo and it matches against a database of industrial components. Better for bearings, seals, and electrical components than for brand-specific ag parts, but worth trying when other methods fail.
Tensara — Snap a photo, scan a barcode, or speak a part number. AI identifies the part and returns specs, cross-references, and replacement options. Newer platform but gaining traction in the industrial parts space.
Tip: When using Google Lens on a rusted or dirty part, clean the area around any stamped numbers first. Even partial numbers help — search "RE559485" on eBay and you'll find the part. Search "John Deere RE559" and you'll find it plus compatible variants.
eBay Search Strategies That Actually Work
Most people search eBay by description — "john deere sprayer sensor" — and get 5,000 irrelevant results. Here's how to search like a parts dealer:
Search by exact part number. Type the OEM number in quotes: "KK12928" or "RE559485". This finds listings where the seller put the factory number in the title, which is how most NOS dealers list.
Use wildcard searches. If you only have a partial number, use eBay's wildcard: KK129* returns all variants of that prefix. This helps when you know the prefix but not the suffix.
Search completed listings. Check "Sold Items" in the filter panel. This shows what the part actually sold for — useful for pricing and for finding sellers who specialize in that part number. Message the seller directly even if the listing is ended; they may have another one.
Save your searches. eBay lets you save search alerts. Set up an alert for a part number you need, and eBay emails you when a new listing matches. This is how NOS dealers find parts — they wait for inventory to surface, sometimes for months.
Check our eBay store first. We list NOS and used ag parts at the TheRustySiloTrader eBay Store with OEM part numbers in every title. Search the store by part number — if we have it, it'll show up.
Cross-Reference Tools
A Case IH part number often crosses to a New Holland or MacDon number. A Timken bearing crosses to SKF, Federal Mogul, and Enduro. These tools find those matches:
Parts-CrossReference.com — 500,000+ part numbers across agriculture, construction, and industrial equipment. Free to search. Covers John Deere, Case IH, Caterpillar, and 200+ other brands. Start here when you have an OEM number and need aftermarket or cross-brand equivalents.
PartsCrossReference.com — Subscription-based, but the most comprehensive interchange tool for bearings, seals, drive belts, and filters. If you work with Timken, SKF, CR, or National numbers regularly, the subscription pays for itself in time saved.
Our Oil Filter Cross-Reference Guide — Free. Covers WIX, Fram, NAPA, and Fleetguard filter interchanges with micron ratings, thread sizes, and engine applications.

Tip: When calling a salvage yard, have your part number AND equipment model ready. Say: "I need part number RE559485 for a John Deere R4030 sprayer." Specific requests get faster answers than "do you have sprayer parts?"

FAQ
What is the best site for John Deere parts lookup?
The official John Deere Parts Catalog is the most accurate. Enter your model or PIN to see exploded diagrams with part numbers. For used and NOS parts, search eBay by the part number or check our agricultural parts category.
How do I identify a tractor part if the part number is unreadable?
Use Google Lens on your phone — point the camera at the part and it matches the shape against product images. For Case IH and New Holland parts, use the visual search tool on mycnhstore.com. Clean the area around any stamped numbers first; even partial numbers are searchable on eBay.
How do I find a discontinued tractor part?
Start with the OEM part number from the manufacturer's parts catalog. Then search eBay by the exact part number in quotes, check Parts-CrossReference.com for aftermarket equivalents, and call tractor salvage yards directly with the part number. Set up eBay saved search alerts so you're notified when one surfaces. Post on TractorByNet or Yesterday's Tractors forums — someone may have the part or know where to find it.
Are aftermarket tractor parts as good as OEM?
It depends on the part. Filters, bearings, and seals from reputable brands (WIX, Timken, SKF) are generally equivalent to OEM. For precision components like GPS sensors, hydraulic pumps, and electronic control boards, OEM or NOS is safer. Cross-reference tools help you identify quality aftermarket equivalents.
What is NOS tractor parts?
NOS stands for New Old Stock — original manufacturer parts that were never sold or installed. These are factory parts sitting on a dealer shelf or in a warehouse, often for decades. NOS parts are valuable because they are genuine OEM quality and sometimes the only remaining source for discontinued part numbers.
Where can I find free tractor service manuals?
John Deere offers some operator manuals for free through their OMView system — no central search page exists, so search Google for site:manuals.deere.com/omview plus your model (e.g., site:manuals.deere.com/omview 8520 tractor). DeereManual.com has free browsable operator manuals for many JD models. The Internet Archive has community-uploaded PDFs. ManualsLib has 251+ Case IH tractor manuals free to view. For service manuals, the manufacturer's publication site is the official source. Forum members on Yesterday's Tractors and TractorByNet sometimes share manual links.
