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.

2-valve cylinder head

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

Mechanical rotary fuel pump

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

Fixed geometry turbocharger

  • 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

Compact size

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

Engine performance

  • Excellent block loading capability

Additional features

  • Self-adjusting poly-vee fan drive
  • Forged-steel connecting rods
  • Replaceable wet-type cylinder liners
  • Either-side service
  • Optional final fuel filter with water separator and water-in-fuel sensor
  • Optional balancer shafts
