Built on proven PowerTech Plus technology
John Deere has always been ahead of the game when it comes to meeting emissions regulations. We pioneered the use of many advanced technologies with our Tier 3/Stage III A engines and proved their performance in off-highway applications. This gives us a head start for fuel economy as well as delivering higher power bulge, more torque rise, and faster transient response time.
First in the field
John Deere was the first engine manufacturer to take advantage of cooled exhaust gas recirculation (EGR) and variable geometry turbocharger (VGT) technologies in off-highway applications, introducing them with Tier 3/Stage III A emissions regulations. Our engines have a proven record of emissions reduction, best-in-class fuel economy, and rugged durability. When it comes to off-highway performance, other engine manufacturers can only follow in our tracks.
John Deere engines continue to provide the best total fluid economy and value. Our cooled EGR engines operate efficiently with ultra-low sulfur diesel (ULSD) as well as biodiesel blends, providing optimal performance and fuel-choice flexibility.
The jobs that John Deere PowerTech engines tackle every day are as varied as the equipment they power. That's why the John Deere Integrated Emissions Control system optimizes the use of various technologies designed to meet the unique needs of off-highway equipment. PowerTech 4.5L, 6.8L, 9.0L, and 13.5L engines use our proven PowerTech Plus technology, which includes 4-valve cylinder heads, cooled EGR, VGT, air-to-air aftercooling, high-pressure fuel systems, and wet-type cylinder liners.
