  • 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.

  • Cross-flow head design provides excellent breathing from a lower-cost 2-valve cylinder head

  • The timing and fuel injection pressures are optimized to maximize performance and fuel economy at a given rated speed

  • Fixed geometry turbochargers are precisely matched to the power level and application

  • In turbocharged engines, the air is pre-compressed. Due to the higher pressure, more air is supplied into the combustion chamber allowing a corresponding increase in fuel injection which results in greater engine output

  • Mounting points are the same as Tier 2/Stage II engine models

  • Excellent block loading capability

  • Self-adjusting poly-vee fan drive
