Stage V.
  • John Deere has billions of hours of field experience with off-highway diesel engine technologies and launched many of its engines ahead of EPA and EU deadlines, and is ready to meet Stage V emissions regulations using our proven diesel particulate filter (DPF) solutions. In most cases, OEM customers currently using a John Deere engine with a diesel particulate filter (DPF) won’t have to re-engineer machine design to meet the requirements of Stage V regulations. Our engineers continue to employ a global network of technical resources and the latest technology to lower emissions while improving performance and fluid efficiency.
Wastegated turbocharger
  • Wastegated turbochargers are designed to develop more airflow at lower engine speeds to improve low-speed torque. The wastegate control device bleeds off a portion of the exhaust flow at higher engine speeds. Wastegated turbos deliver improved transient response and higher peak torque without compromising engine envelope size. They also provide the lowest installed cost across a given power range.
Exhaust filters
  • These engines utilize a catalyzed exhaust filter that contains a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF). The DOC reacts with exhaust gases to reduce carbon monoxide, hydrocarbons, and some particulate matter (PM). The downstream DPF traps and holds the remaining PM. Trapped particles are oxidized within the DPF through a continuous cleaning process called passive regeneration. Passive regeneration occurs during normal operating conditions when heat from the exhaust stream, and catalysts within the exhaust filter, trigger the oxidation of the trapped PM. If passive regeneration cannot be achieved due to low temperature, load, or speed, then PM is removed using active regeneration — an automatic cleaning process controlled by the exhaust temperature management system.
No exhaust recirculation
  • Simple, low cost solution optimized for these power ratings.
No SCR
  • Simple, no-DEF solution for these power levels.
High-pressure common-rail (HPCR)
  • The HPCR fuel system provides variable common-rail pressure and high injection pressures. It also controls fuel injection timing and provides precise control for the start, duration, and end of injection.
Air-to-air aftercooled
  • This is the most efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs.
2-Valve cylinder head
  • Cross-flow head design provides excellent breathing from a low-cost 2-valve cylinder head.  This less complex design is optimized for these ratings.
Compact size
  • Lower installed cost
  • Mounting points are the same as previous engine models
John Deere electronic engine controls
  • Faster engine control unit (ECU) manages both the engine and the exhaust filter
  • Premium software option integrates with equipment or vehicles to reduce engineering and installation costs
Big-engine durability
  • Replaceable (wet) cylinder liners
  • Oil-cooled pistons with hardened ring groove insert
  • Full flow engine-mounted oil cooler
  • Up to 500-hour oil change
Additional features
  • Grid heater cold start aid
  • Single fluid solution
  • Engine or remote mounted fuel filters
  • Gear-driven auxiliary drives
  • Optional engine mounted exhaust filter
  • High- and low- profile turbo configurations
