Jet fuel capable
  • The John Deere jet fuel capable engines run on military, arctic, and aviation fuel, including Jet A, Jet A-1, JP-5, and JP-8. If you need to switch back to diesel fuel, just fill up the tank and go.
Cooled exhaust gas recirculation (EGR)
  • Cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx
Variable geometry turbocharger (VGT)
  • Varies exhaust pressure based on load and speed to ensure proper EGR flow and best-in-class fuel economy.
High-pressure common-rail (HPCR) and engine control unit (ECU)
  • The HPCR fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures up to 1,600 bar (23,000 psi). It also controls fuel injection timing and provides precise control for the start, duration, and end of injection.
4-valve cylinder head
  • The 4-valve cylinder head provides excellent airflow by utilizing a cross-flow design
Air-to-air aftercooled
  • This is the most efficient method of cooling intake air to help reduce engine emissions. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs
Compact size
  • Horsepower/displacement ration is best-in-class
  • Lower installed cost
  • Mounting points are the same as previous engine models
John Deere electronic engine controls
  • Electronic engine controls monitor critical engine functions, providing warning and/or shutdown to prevent costly engine repairs and eliminate the need for add-on governing components, all lowering total installed costs.
Additional features
  • Self adjusting poly-vee fan drive
  • Single-piece low-friction steel piston
  • Low-pressure fuel system with electrical transfer pump and "auto-prime" feature
  • Directed top-liner cooling
