The John Deere advantage
Our Integrated Emissions Control system for Final Tier 4/Stage IV is an optimized platform utilizing a variety of emissions control components, such as cooled EGR, smart exhaust filters, and SCR technology. The entire system is optimized to meet emissions regulations while delivering maximum performance, reliability, and durability.
Our cooled EGR approach leverages the proven fuel efficiency of our PowerTech engine platform. We continue to develop solutions that consider not only fuel economy, but also total fluid economy. John Deere Final Tier 4/Stage IV engines will meet or improve upon the current total fluid economy of our Interim Tier 4/Stage III B engine models.
We’ve used cooled EGR since 2005 and have established a proven record of reliability. We have accumulated significant operating hours with our smart exhaust filter technology, and have a dedicated in-house aftertreatment team optimizing our own SCR solution. All components used in our Integrated Emissions Control system are designed to handle the rigors of off-highway applications.
John Deere designs, manufactures, and services the engine, drivetrain, exhaust filter, ECU, cooling, and other vehicle systems as part of a complete equipment package. This integrated process maximizes performance, operator convenience, total fluid economy, and overall value to the customer.
