Interim Tier 4/Stage III B Technologies

Right Technology. Right Now.
By choosing EGR first, John Deere proved we could meet the near-zero levels of Interim Tier 4/Stage III B emissions regulations for off-highway equipment with diesel engines without the addition of SCR. Our approach uses cooled exhaust gas recirculation (EGR) for NOx reduction and an integrated exhaust filter for particulate matter (PM) reduction. It is simple to install, operate, and maintain while delivering the power, fuel efficiency, reliability, and low cost of ownership you've come to expect from John Deere.

PowerTech PSX engines
93-448 kW (125-600 hp)
For ultimate performance in off-highway applications that take you up and down steep grades at high altitudes. Or when you simply want maximum transient response and low-speed torque. A PowerTech PSX 6.8L, 9.0L, or 13.5L engine is exactly what you need. Along with proven PowerTech Plus technology, all three displacements feature series turbochargers that improve performance and responsiveness.

PowerTech PVX engines
93-224 kW (125-300 hp)
When you need unparalleled performance, PowerTech PVX 4.5L, 6.8L, or 9.0L engines are the perfect fit for your application. These displacements utilize our proven PowerTech Plus technology with variable geometry turbocharging (VGT) to improve performance and combustion efficiency, reduce emissions, and increase fuel economy.

PowerTech PWX engines
63-91 kW (85-122 hp)
Equipment owners who want straightforward, cost-effective power rely on PowerTech PWX 4.5L engines. These compact engines blend proven cooled EGR technology with simple and reliable wastegated turbocharging to maintain transient response and peak torque in all operating conditions. Their 4-valve cylinder heads also provide excellent airflow for greater low-speed torque. Multiple rated speeds let you fine-tune your engine selection to reduce noise and fuel economy.

PowerTech M engines*
36 – 55 kW (48-74 hp)
The PowerTech M 2.4L and 4.5L engines are the simplest of the PowerTech family; these engines have 2-valve heads, fixed geometry turbochargers, and mechanical fuel systems. PowerTech M engines are perfect for less demanding applications. Their mechanical controls are simple to operate and maintain.

PowerTech E engines*
45-49 kW (60-66 hp)
The PowerTech E 2.4L and 4.5L engines also have 2-valve heads and fixed geometry turbochargers, but introduce full-authority electronic controls, more sophisticated fuel delivery and electronic unit pump fuel systems.

*The PowerTech M 2.4L and PowerTech E 2.4L engine lineups below 56 kW (75 hp) meet Interim Tier 4 and Stage III A emissions regulations and the PowerTech M 4.5L engine meets Interim Tier 4 emissions regulations without the addition of cooled EGR or an exhaust filter.
