Engines with Tier 3-Stage IIIA/MAR-I Emission Control

BM010705-UN-22JAN16

The emission control programs set maximum emission limits for engines, reducing the environmental impact of vehicles and machinery on air quality.

Tier 3-Stage IIIA certified engines meet the requirements of US EPA Tier 3, EU Stage IIIA, and PROCONVE MAR-I regarding the maximum emission limits for agricultural machinery.

The programs consider both machinery and fuel as an integrated system. Therefore, it is essential the correct use and maintenance of the machine.

Fuel quality and sulfur content must comply to the specifications described in this Manual.

IMPORTANT: If the engine or the engine auxiliaries fail during the lifespan, contact your John Deere dealer for proper maintenance to ensure the correct emission control.
