John Deere Power Systems
John Deere Power Systems (JDPS) manufactures and markets 30 kW to 448 kW (40 hp to 600 hp) industrial diesel engines and 56 kW to 559 kW (75 hp to 750 hp) marine diesel engines, as well as drivetrain components for use in a variety of off-highway applications. JDPS serves the agriculture, construction, generator-set, industrial, marine, mining and a wide variety of other off-highway markets.
Interim Tier 4/Stage III B solutions
The complete line of John Deere Interim Tier 4/Stage III B diesel engines is built upon simple, fuel-efficient and field-proven technologies that meet increasingly stringent emissions regulations without sacrificing optimized engine performance, operating efficiency, long term durability or operator convenience. Power ratings range from 36 kW to 448 kW (48 hp to 600 hp).
For engines 56 kW (75 hp) and above, John Deere started with their proven PowerTech™ Plus Tier 3/Stage III A engine platform — which includes cooled exhaust gas recirculation (EGR) for NOx control — and added an exhaust filter for reducing particulate matter. Displacements in this power range include the 4.5L, 6.8L, 9.0L and 13.5L in-line, four- and six-cylinder engines, all of which feature a four-valve cylinder head, high-pressure fuel system, turbocharging and an air-to-air aftercooling system.
Engines between 56 kW (75 hp) and 129 kW (173 hp) are available in 4.5L and 6.8L displacements and come equipped with either a wastegate or variable geometry turbocharger, depending upon the size of the engine. Compared to John Deere’s larger engines, models between 56 kW (75 hp) and 129 kW (173 hp) feature smaller exhaust filters that can be engine-mounted or remote-mounted for increased flexibility. Engines in this power range use an in-cylinder dosing strategy, while the 130 kW (174 hp) and above engines use an external dosing system integrated into the exhaust system.
The John Deere PowerTech M 2.4L engine meets Interim Tier 4 and Stage III A emissions regulations and the PowerTech M 4.5L meets Interim Tier 4 emissions regulations without the use of cooled EGR or an exhaust filter.

Final Tier 4/Stage IV technology path
John Deere will continue its planned building-block approach to meet Final Tier 4 and Stage IV emissions regulations. To achieve regulatory compliance, John Deere developed the Integrated Emissions Control system — a solution that optimizes engine performance, operating efficiency and long term durability.
For Final Tier 4/Stage IV, John Deere will offer its familiar PowerTech displacements of 2.9L, 4.5L, 6.8L, 9.0L and 13.5L. Power ratings throughout the lineup will, in some cases, be higher than previous offerings.
John Deere Final Tier 4/Stage IV engine performance will meet or exceed that of the John Deere Interim Tier 4/Stage III B engines. The Final Tier 4/Stage IV engines will continue to provide the same or higher levels of power density and torque along with transient response that meets or exceeds that offered with Interim Tier 4/Stage III B engines.
In addition, John Deere Final Tier 4/Stage IV engines will meet or improve upon the total fluid economy of Interim Tier 4/Stage III B engine models. When combined with cooled EGR technology, the Integrated Emissions Control system will enable John Deere engines to meet emissions requirements while utilizing less diesel exhaust fluid (DEF) than alternative Interim Tier 4/Stage III B SCR solutions. DEF consumption with John Deere Final Tier 4/Stage IV engines will be 1 to 3 percent of diesel fuel consumption depending on the application. Lower DEF consumption means DEF tank size can be smaller—minimizing the impact on vehicle applications while extending DEF filter service intervals and reducing operator involvement. Increased pressures created by John Deere’s Final Tier 4/Stage IV high-pressure fuel systems will reduce engine-out PM and extend intervals between an active exhaust filter regeneration.
John Deere engines below 56 kW (75 hp) will meet Final Tier 4/Stage IV regulations using an Integrated Emissions Control system consisting of an exhaust filter without cooled EGR or SCR.
