John Deere recently reached a significant milestone. We’re pleased to announce that we started production of our larger displacement Final Tier 4/Stage IV off-highway diesel engines, models meeting emissions regulations that took effect Jan. 1 for engines 130 kW (174 hp) and above. We’re right on time and ready to help our OEM customers integrate these certified engines into a variety of equipment.
Engines recently entering production include PowerTechTM PVS and PowerTech PSS 6.8L, PowerTech PSS 9.0L and PowerTech PSS 13.5L models with power ratings from 138 kW (185 hp) to 448 kW (600 hp). These engines feature an Integrated Emissions Control system consisting of a diesel oxidation catalyst (DOC)/diesel particulate filter (DPF) and selective catalytic reduction (SCR).
Certified as compliant with Environmental Protection Agency (EPA), European Union (EU) and California Air Resources Board (CARB) regulations in 2013, these engines achieve the required 80 percent reduction in nitrogen oxides (NOx) from previous Interim Tier 4/Stage III B requirements. We’re confident that they will do so while delivering the performance, uptime and low operating costs that OEM customers and equipment operators need.
