Stage V engine technology

PowerTech EWX

EWX engines are compact, powerful, cost-effective, and simple to install without requiring cooled EGR or SCR. Our straightforward PowerTech EWX 2.9L and 4.5L engines have 2-valve cylinder heads, high-pressure common-rail fuel systems, and full authority electronic controls. They use simple wastegate turbocharging to maintain transient response and peak torque in all operating conditions.

PowerTech PWS

PWS 4.5L and 13.6L engines combine advanced combustion technologies, enhanced engine calibration, and simple wastegate turbocharging. PWS engines feature PowerTech Plus technology with a DOC/DPF and an SCR system that reduce emissions while maximizing performance.

PowerTech PVS

PVS 6.8L engines deliver more power, torque, and fluid economy. They utilize our proven PowerTech Plus technology with variable geometry turbocharging, a DOC/DPF, and an SCR system to improve combustion efficiency, reduce emissions, enhance performance, and improve fluid economy.

PowerTech PSS

PSS engines provide a powerful combination of power density, performance, and fluid efficiency. For ultimate performance in off-highway applications, PowerTech PSS 4.5L, 6.8L, 9.0L, 13.5L, and 13.6L engines can handle almost any job. All displacements feature series turbochargers to deliver excellent performance and responsiveness. PSS engines feature proven PowerTech Plus technology that includes a DOC/DPF and an SCR system designed specifically for off-highway applications.

Proven performance

Off-highway experience

John Deere has billions of hours of field experience with off-highway engine technologies.
We use an exhaust system strategy that is designed to be transparent to the operator, without impacting machine performance. Our proven aftertreatment solution has logged more than 1 billion hours of operation on hundreds of internal and external OEM applications.

Turbocherged power

John Deere engines deliver fast transient response and high peak torque thanks to tailored turbocharging technologies. We use a combination of wastegate, variable geometry, and series turbochargers to meet your application needs.

Reliable uptime

Day-to-day reliability

John Deere engines feature top-liner cooling, efficient lubrication, and robust cooling systems for reliable operation.

Long-haul durability

Heavy-duty, oversized components and wet-type cylinder liners provide long engine life. John Deere engines are designed for rugged applications.

Extreme conditions

John Deere engines are built to operate in hot and dry, subzero, and humid climates as well as high altitudes. The engine control unit (ECU) monitors and protects engine components in these extreme conditions.
In regions where fuel quality may vary, John Deere protects the engine with two-stage fuel filtration and water detection.

Efficient operation

Fuel efficiency

The efficient design of the John Deere combustion chamber with high-ring pistons helps deliver excellent fuel economy.

Less DEF

Use of cooled EGR reduces nitrogen oxides (NOx) out of the engine. This enables the use of a smaller selective catalytic reduction (SCR) system and lower diesel exhaust fluid (DEF) consumption. John Deere engines with EGR use 1 to 3 percent less DEF compared to non-EGR engines.

Life cycle costs

Reliable operation, low maintenance, long engine life, and exceptional fluid economy lead to low cost of operation with John Deere engines.

Long service intervals

500-hour interval for oil and fuel filters, 1,500 hours for OCV, 4,500 hours for DEF supply module filter, 6,000 hours for coolant, and up to 15,000 hours for DPF. No service required on DEF header filter.

Easy integration

Stage V ready solution

No re-engineering required. No hardware changes.

John Deere Stage V engines have the same engine envelope size and use the same mounting points as John Deere Stage IV engines. Your machines have dual EPA and EU certification.

Integration flexibility

With multiple parts options and various aftertreatment outlet and inlet choices, OEMs may have to do less modification to integrate John Deere engines. Easy configurability saves development costs and reduces delivery time to market.
Single-side service points make installation and maintenance easier.
