How To Find Tractor Parts By Model Number

How To Find Parts By Model Number — A Step-By-Step Guide

Your equipment's model number is the fastest path to finding compatible parts. Unlike browsing generic categories and hoping for a match, searching by model number takes you directly to components engineered for your specific machine. Whether you're maintaining a John Deere row crop tractor, a Kubota compact utility, a Caterpillar excavator, or a Case IH combine, the model number is your starting point for every parts search.

This step-by-step guide shows you exactly how to find your model number, how to use it to search for parts, and how to avoid the common mistakes that lead to ordering the wrong component. Field & Fleet Parts makes the whole process simple with our model-based search tool at fieldandfleetparts.com.

Step 1: Locate Your Equipment's Model Number

The model number and serial number are typically found on a metal identification plate attached to the machine. The exact location varies by brand and equipment type:

• John Deere tractors: identification plate on the left side of the frame, near the front axle, or on the instrument panel

• Kubota tractors: plate on the rear of the engine block or the lower left side of the dashboard pillar

• Case IH tractors: plate on the right-hand side of the rear frame or inside the cab door

• New Holland tractors: identification plate near the front of the frame or under the hood

• Caterpillar equipment: machine information plate in the cab or on the frame rail near the operator's station

• Massey Ferguson tractors: plate on the instrument console or the right side of the transmission housing

Write both the model number and the serial number down and keep them with your service records. You'll need them repeatedly throughout the life of the machine.

Step 2: Understand What's in the Model Number

Equipment model numbers aren't random — they encode important information about the machine. Learning to read them helps you verify you're looking at the right parts list.

For John Deere, a model like 6120M tells you the approximate engine horsepower range (6000 series = 100+ hp), the generation, and the feature tier (M = mid spec). For Kubota, an M7-151 indicates the M series (mid-size utility), 7th generation, 151 horsepower. For Caterpillar, a 320 excavator name tells you approximate operating weight class.

Mid-production engineering changes can also affect part compatibility within the same model name. That's why the serial number matters as much as the model name — it pins down exactly which production run your machine came from.

Step 3: Use the Model Number to Search for Parts

With your model number and serial number in hand, you have several ways to find compatible parts:

Option 1 — Use Field & Fleet Parts' Search By Model tool: Visit fieldandfleetparts.com and use the equipment selector to choose your machine type, brand, and model. This filters our entire catalog to show only parts confirmed compatible with your equipment.

Option 2 — Use the manufacturer's parts catalog: Most major brands publish searchable online parts catalogs (John Deere's Parts Advisor, Kubota's Parts Lookup, CNH's PartsCatalog, etc.). These catalogs are organized by assembly and show illustrated parts diagrams with individual part numbers.

Option 3 — Contact our support team: If you're having trouble navigating the search or the part you need isn't showing up, our knowledgeable staff can look it up for you. Call us at +1 (415) 612-5914 or reach us via WhatsApp.

Step 4: Cross-Reference the Part Number Before Ordering

Once you've identified the part number from the catalog or diagram, take a moment to verify it before placing your order:

• Confirm the part number applies to your serial number range — the parts catalog will list serial number breakpoints where part numbers changed

• Check for superseded numbers — if the original part number has been replaced, the current number is what you need

• If ordering aftermarket, verify the aftermarket listing includes your OEM part number as a cross-reference

This extra 60 seconds of verification prevents the most common ordering mistakes.

Step 5: Understand Model Number Variations and Sub-Models

Many tractor models were sold in multiple configurations that look identical externally but differ internally. Sub-models, regional variants, cab vs. open station versions, and different transmission options can all affect part compatibility.

For example, a John Deere 5075E with a PowrReverser transmission uses different clutch components than the same model with a Collar Shift transmission. A Kubota M6060 with ROPS uses different cab components than the M6060 with an enclosed cab. Always identify your sub-model configuration along with the base model.

Keeping a Parts Reference Sheet for Your Equipment

Once you've done the work of locating your model numbers, serial numbers, and key part numbers, create a simple reference sheet for each piece of equipment you own or operate. Include:

• Machine make, model, and sub-model

• Serial number and build date

• Engine model and serial number (often different from the machine serial)

• Frequently replaced parts with their part numbers: oil filter, hydraulic filter, air filter, belts, and common wear items

Store a copy in the cab and another in your shop. Having this information instantly available means you can order parts in minutes rather than spending an hour hunting for identification plates.
