The John Deere Integrated Emissions Control system for Final Tier 4/Stage IV is optimized to meet emissions regulations while delivering improved performance, uptime, and efficiency.

Feel the performance
John Deere power responds to your every command. It gives you low-end torque to attack heavy loads without stalling or lugging the engine.

Run with confidence
John Deere engines start when you need them, work reliably in tough conditions, and help you complete critical jobs on schedule.

Manage your bottom line
With low operating costs and proven efficiency, John Deere engines earn their way into your business. John Deere Final Tier 4/Stage IV engines demonstrate lower total fluid consumption compared to the previous Tier. Longer service intervals save you time and money on maintenance.

PowerTech EWX: 37-55 kW (48-74 hp)

PowerTech EWX: 37-55 kW (48-74 hp)
Compact, powerful, and cost-effective

Our straightforward PowerTech EWX 2.9L and 4.5L engines have 2-valve cylinder heads, high-pressure common rail fuel systems, full-authority electronic controls, and proven exhaust filters.
These compact, cost-effective engines don’t require cooled EGR or SCR. They use simple wastegate turbocharging to maintain transient response and peak torque in all operating conditions.


PowerTech PWL : 63-104 kW (85-140 hp)

PowerTech PWL : 63-104 kW (85-140 hp)
Efficiency, performance, and simplicity

The PowerTech PWL 4.5L engines combine advanced combustion technologies, enhanced engine calibration, and simple wastegate turbocharging. Pairing our proven PowerTech Plus technology with a DOC and SCR system, these engines offer a compact power solution. PowerTech PWL engines produce near-zero levels of PM without a filter thanks to an optimized combustion system and engine calibration. Remaining PM and other hydrocarbons are oxidized passively in a flow-through DOC without the need for regeneration.


PowerTech PVS: 104-187 kW (140-250 hp)

PowerTech PVS: 104-187 kW (140-250 hp)
More power, torque, and fluid economy

PowerTech PVS 6.8L engines provide reliable power for a wide range of applications. They utilize our proven PowerTech Plus technology with variable geometry turbocharging (VGT) and an SCR system to improve combustion efficiency, reduce emissions, enhance performance, and improve fluid economy.


PowerTech PSS: 93-448 kW (125-600 hp)

PowerTech PSS: 93-448 kW (125-600 hp)
Best power density, performance, and fluid efficiency

For ultimate performance in off-highway applications, PowerTech PSS 4.5L, 6.8L, 9.0L, or 13.5L engine can do almost any job. They can handle steep grades at high altitudes and deliver maximum transient response and low-speed torque. Along with proven PowerTech Plus technology and an SCR system designed specifically for off-highway applications, all displacements feature series turbochargers that improve performance and responsiveness.
