Construction & Agricultural Machinery AdBlue (SCR), DPF & DTC Removal Emulators
AdBlue (DEF) faults and blocked DPF filters can bring construction equipment and farm machinery to a standstill at the worst possible moment. Our plug-in emulator devices keep your machines running without interruption — whether on a remote job site or in the middle of harvest season. 85 products.

What Is an Emulator for Construction & Agricultural Machinery?
Modern construction equipment and agricultural tractors are fitted with SCR (Selective Catalytic Reduction) and DPF (Diesel Particulate Filter) systems to meet Euro 4, Euro 5, Euro 6 and Euro 6.2 emission standards. The SCR system uses AdBlue — a 32.5% urea solution also known as DEF (Diesel Exhaust Fluid) in North America — to convert harmful NOx gases into harmless nitrogen and water. In the demanding environments of construction sites and farmland, AdBlue sensor failures, DPF blockages and ECU fault codes are common problems. Our emulator devices are compact electronic modules that plug directly into the machine's CAN-bus circuit, simulating the signals from the disabled system so the engine continues to operate at full power without entering limp mode or triggering a forced shutdown.
Brands, Emission Standards and Systems Covered
This category covers a wide range of construction and agricultural machinery brands including Case, Deutz, New Holland, John Deere, Kubota, Perkins, Atlas Copco, Doosan, Kobelco, Landini and Ford. Products span the full spectrum from Euro 4 through Euro 6.2. Supported emission control systems include: AdBlue SCR removal, DPF removal, NOx sensor emulation and DTC fault code erasing. Example products in this range include SCR bypass emulators for Case Euro 4/5/6 excavators and tractors, DPF soot reset and OBD fault code erasers for Deutz-engine machines, and combined SCR+DPF removal emulators for Atlas Copco Scania Euro 6.2 compressors.
Why Choose an Emulator for Your Construction or Farm Machine?
Emulator devices offer a practical, non-invasive solution to emission-system faults that would otherwise leave your machine parked and costing you money. Key advantages include protection against AdBlue (DEF) sensor and dosing pump failures that would otherwise trigger an engine shutdown; elimination of power loss and unplanned regeneration stops caused by DPF blockages; seamless integration with the original ECU on Euro 4, Euro 5 and Euro 6 machines without altering factory firmware; model-specific designs for brands such as Case, John Deere, Deutz and New Holland that prevent false fault code triggers; significantly reduced servicing downtime and spare-part costs — especially critical on remote job sites and isolated farmland; and NOx sensor emulation that resolves limp-mode conditions caused by sensor failure, restoring full engine output.
How to Select the Right Emulator
Choosing the correct emulator for your construction machine or tractor starts with knowing the manufacturer brand, engine type, emission standard and which system is at fault. First, check the machine's registration document or engine plate to identify the Euro norm. Use an OBD diagnostic reader to confirm whether the fault lies in the AdBlue SCR system, the DPF filter or only in stored DTC fault codes. Then check the compatibility list on the product page — for example, a Case Euro 5 AdBlue Removal Emulator and a Case Euro 6 AdBlue Removal Emulator are designed for different ECU architectures and cannot be used interchangeably. If you are unsure, contact our live support with the brand, model year and fault code, and we will confirm compatibility before you order.
Installation, Shipping and Warranty
All emulators in this category follow a plug-and-play installation principle, connecting via the OBD port or the relevant sensor connector — no mechanical disassembly required. Installation can be carried out by any competent auto-electrician or workshop technician with basic electrical knowledge. Orders for in-stock items are dispatched within one business day and ship with a tracking number for real-time monitoring. Every product carries a warranty; full terms and duration are detailed on the individual product page. For post-installation technical questions, our support team is available via email and WhatsApp during business hours.
Frequently Asked Questions
Is there an AdBlue removal emulator compatible with my Case Euro 6 excavator?
Yes — we stock dedicated SCR NOx bypass emulators for Case Euro 6 excavators. Because ECU variants can differ between production years, we recommend providing your machine's serial number or ECU code via the product page support chat so we can confirm the exact match before you order.
How does a DTC fault code eraser work on a Deutz-engine machine?
The Deutz DTC Fault Code Eraser connects via the OBD socket and clears both active and stored emission-related fault codes from the ECU. This takes the machine out of limp (emergency) mode and restores the normal power curve. Crucially, it does more than simply clear codes — it also signals to the ECU that the absence of a NOx or DPF sensor reading is acceptable, preventing the fault from being re-triggered.
Will fitting an emulator affect my tractor or construction machine's warranty?
The impact on manufacturer warranty varies by brand and individual policy. As a general rule, installing an emulator may place the affected system outside the scope of the original warranty, and this decision rests with the machine owner. For machines that are already out of warranty or used purely in commercial off-road applications, emulator use is a widely adopted and practical solution. We recommend consulting your authorised dealer for definitive guidance on your specific machine.
How quickly will my order be delivered?
In-stock emulators are dispatched within one business day. Delivery typically takes 1–3 business days depending on your location. A tracking number is sent to your email address as soon as the parcel is collected by the carrier.
My John Deere Euro 5 tractor has both an SCR fault and a DPF fault — is there a combined emulator?
Yes, several products in this range are combined emulators that bypass both the SCR and DPF systems simultaneously — our Atlas Copco Scania Euro 6.2 SCR+DPF Removal Emulator is one example. To check whether a combined solution is available for your specific John Deere Euro 5 model, use the product search or contact support with the brand and engine code — that is all we need to advise you.
Are emulators legal to use on construction and agricultural machinery?
The legal position depends on how and where the machine is operated. Construction equipment and agricultural machinery used exclusively on private land, job sites or closed areas — where road-use emission testing does not apply — is a common and practical use case for emulators. For machines that operate on public roads and are subject to roadworthiness or emissions inspections, legal responsibility rests entirely with the operator. We recommend checking the applicable regulations in your country before fitting any emulator to a road-registered machine.
