Deere 13.5L Tier 3 Certified
John Deere Power Systems said its PowerTech Plus 13.5L engine has been Tier 3 certified by the Environmental Protection Agency (EPA). The 13.5L engine is the fourth model in the John Deere line to receive Tier 3 certification, joining the PowerTech Plus 4.5L, 6.8L, and 9.0L engines.
The 13.5L engine features a power range of 350 hp to 600 hp and employs emissions technology that includes engine electronics, cooled exhaust gas recirculation and variable geometry turbocharging. Limited production quantities of the PowerTech Plus 13.5L engine began shipping to OEMs in November 2005.
Tier 3 regulations for 175 hp – 750 hp engines began taking effect in January 2006 and are aimed specifically at reducing oxides of nitrogen (NOx) in non-road applications.
