John Deere Power Systems (JDPS) will display Final Tier IV/Stage IV off-highway diesel engines in booth 83718 at ConExpo-Con/AGG 2014. JDPS will showcase 2.9L to 13.5L engines that deliver responsive performance, reliable uptime and a low cost of operation.

For Final Tier IV/Stage IV, John Deere continued with its planned approach by developing the integrated emissions control system, which encompasses a variety of aftertreatment and emissions-reduction component combinations. Integrated emissions control system technology configurations are tailored to meet regulations and customer needs in each power range.

John Deere is offering three integrated emissions control system configurations for Final Tier IV/Stage IV:

• For the 48 to 74 hp (36 to 55 kW) power range, John Deere is offering engine models using an exhaust filter that contains a diesel oxidation catalyst/diesel particulate filter (DOC/DPF) without cooled exhaust gas recirculation (EGR) or selective catalytic reduction (SCR).

• In the 75 to 140 hp (56 to 104 kW) power category, the PowerTech PWL 4.5L engine is equipped with cooled EGR and an integrated emissions control system configured with SCR and a DOC.

• Engines in the 125 hp (93 kW) and above power range will feature an integrated emissions control system consisting of cooled EGR, a DOC/DPF and SCR.

All John Deere integrated emissions control system configurations are designed to meet the demands of off-highway applications. Regardless of power range and integrated emissions control system configuration, John Deere engines offer responsive performance, reliable uptime and a low cost of operation, according to the manufacturer.

JDPS also will display Funk drivetrain components. Funk transmissions, axles, pump drives and planetary drives provide performance, reliability and durability to meet customer needs.
