The global market for agricultural and construction machinery parts is massive—and unfortunately, that makes it a prime target for counterfeit products. As one of the most recognized brands in the world, John Deere is frequently imitated by dishonest manufacturers looking to profit from fake components.
Installing counterfeit parts can lead to early wear, reduced performance, and even major equipment failure. In this article, we’ll break down the 5 most commonly counterfeited John Deere parts, explain how to identify fake components, and highlight the difference between counterfeit and quality aftermarket alternatives.
1. Engine Oil and Fuel Filters
Why they’re counterfeited:
Filters are high-volume consumables that need frequent replacement—making them a profitable target for counterfeiters.
How to spot a fake:
- Low-quality or blurry packaging print
- Missing or incorrect John Deere part numbers and logos
- Noticeably lighter weight than OEM
- Poor-quality metal or inconsistent welds
2. Drive Belts
Why they’re counterfeited:
Belts are essential and widely used, especially in John Deere’s 6R and 8R tractor series. Original belts are expensive, so cheap fakes flood the market.
How to spot a fake:
- No molded part number or branding
- Rubber feels too soft or unusually stiff
- Incorrect size or profile
- Fast wear after installation
3. Electronic Control Units (ECUs)
Why they’re counterfeited:
ECUs are expensive, complex parts that are critical to machine performance. Counterfeits can cause serious electronic faults.
How to spot a fake:
- Cheap-looking plastic housing
- Missing or incorrect serial numbers
- Odd fonts or spelling errors on the label
- Wrong firmware (only revealed during installation)
4. Fuel Injectors
Why they’re counterfeited:
Fuel injectors are high-value, high-precision parts—and poorly made copies can damage your engine.
How to spot a fake:
- No engraved part numbers or manufacturer logo (Bosch, Denso, etc.)
- Unsealed or generic packaging
- QR code doesn’t scan or leads nowhere
- Significant differences in weight or nozzle design
5. Starters and Alternators
Why they’re counterfeited:
Electric components are expensive and often compatible across models, making them a favorite target for counterfeiters.
How to spot a fake:
- Missing or sloppy markings on the housing
- Low-quality terminals or loose connections
- Noticeably lighter than original parts
- No documentation or warranty card
Not All Non-Original Parts Are Fakes
Let’s be clear: not every non-original part is a counterfeit. There’s a huge difference between counterfeit products and legitimate aftermarket parts.
- Counterfeit parts pretend to be original—they copy the packaging, logos, part numbers, and even the look of OEM components, often with dangerously poor build quality.
- Aftermarket parts, on the other hand, are produced legally by third-party manufacturers and openly sold under their own brand names.
Trusted aftermarket and OEM brands include:
- Fleetguard – filters (OEM supplier for Cummins)
- Donaldson – filters and air systems
- Gates – belts and hoses
- Delco Remy – starters and alternators
- A&I Products – a wide range of John Deere-compatible components
These companies do not pretend to be John Deere. They offer high-quality alternatives that meet or exceed OEM specifications—and often at a better price.
