Emissions Information

The Western Power Products commitment to clean air does not end with offering best-in-class EPA certified, fuel efficient John Deere and Yanmar diesel engines. It extends to helping OEMs and end-users access information that will assist them in understanding and complying with regulations applicable to their businesses. We invite you to explore this emissions section and visit the linked sites for more information.However, emissions regulations driven by Federal and State clean air standards and local Air Pollution Control District interpretations are very complex. The links are provided as an information service only and Western Power Products, Inc. is not responsible for the content of any referenced or linked off-site page and is not liable for that content. Users specifically seeking information about California emissions regulation requirements administered by the California Air Resources Board (CARB) are reminded that individual local air pollution control districts (APCDs) have the final say about compliance in their respective areas. Users must contact their local APCD for answers to questions concerning specific compliance issues.

Q. HOW WILL JOHN DEERE POWER SYSTEMS MEET STAGE V EMISSIONS REGULATIONS?

A. As both an engine and machine manufacturer, John Deere boasts a remarkable 1 billion hours of global experience with diesel particulate filter technologies (DPF) — this extensive knowledge is the foundation of the proven emissions solutions provided to OEM customers. John Deere has employed DPF technology since Interim Tier 4/Stage IIIB.
John Deere Power Systems continues to lead its customers seamlessly through the upcoming Stage V transition, thanks to its global field-tested experience. This valuable experience on hundreds of internal and external OEM applications has resulted in a tested DPF solution that increases uptime and offers the day-to-day reliability and durability users have come to expect from John Deere.
We continuously develop and test technologies to meet emissions regulations and refine our aftertreatment packages based on our field-proven solutions. For Final Tier 4/Stage IV regulations, we added a selective catalytic reduction (SCR) system to our PowerTech™ engine platform in engines 56 kW (75 hp) and above.

Q. HOW WILL THESE EMISSIONS PACKAGES IMPACT OEM EQUIPMENT DESIGNS?

A. In most cases, OEM customers currently using a John Deere engine with a DPF won’t have to reengineer machine design to meet Stage V requirements.
In addition, the engineering integration team at John Deere Power Systems is built to make sure its engines and their aftertreatment systems can be properly integrated with OEM equipment. We have been using DPF technology since 2011, and we’re well-positioned to help OEMs easily transition to the Stage V-compliant packages.
We have extensive experience with the development and integration of DPFs in both John Deere and OEM equipment, with more than 1 billion DPF operating hours in the field. 

Q. WHICH JOHN DEERE PRODUCTS ARE STAGE V CERTIFIED?

A. John Deere Power Systems continues to lead its OEM customers seamlessly through the upcoming emissions transition with a lineup of engines that have received Stage V certification. This includes its variable-speed engine families below 56 kW (75 hp) and above 130 kW (174 hp) as well as its constant speed engine families. The industrial Stage V lineup from John Deere offers ratings from 36 to more than 500 kW (48 to more than 670 hp) with displacements of 2.9L through the upcoming 13.6L
