John Deere displayed Final Tier 4/Stage IV Engine Technology at Agritechnica 2013

HANOVER/GERMANY, December 3, 2013 - John Deere Power Systems has exhibited its whole Final Tier 4/Stage IV diesel engine range featuring the Integrated Emissions Control system at Hanover’s Agritechnica in November. In addition to powering a large variety of John Deere equipment, the company also develops, designs and manufactures engines for a wide diversity of agricultural applications: spreaders, feeder mixers, vineyard tractors, harvesters, sprayers… For each type of agricultural equipment, JDPS can offer the engine adapted to the manufacturer's requirements and the needs of the end buyer.

“We began the design process by listening to our customers, and we have worked with them every step of the way to ensure our solutions deliver the industry-leading performance and low operating cost they expect from John Deere,” said Geoff Stigler, manager of worldwide marketing for John Deere Power Systems. “Our building-block approach has enabled us to adopt the best available technologies to meet each new regulatory tier, and this continues with Final Tier 4/Stage IV.”
In July 2013, JDPS announced that the company’s engine lineup 130 kW (174 hp) and above has received U.S. Environmental Protection Agency (EPA) Final Tier 4, European Union (EU) Stage IV and California Air Resources Board (CARB) emissions certification. The PowerTechTM PVS 6.8L, PowerTech PSS 6.8L, PowerTech PSS 9.0L and PowerTech PSS 13.5L models are the first John Deere off-highway engines to receive Final Tier 4, Stage IV and CARB emissions certification in the 130 kW to 560 kW (174 hp to 750 hp) power category.

“The certifications of our PowerTech engines 130 kW (174hp) and above are tremendous milestones for John Deere, and confirm that our customers can be confident in our tailored Integrated Emissions Control systems, which deliver innovative technologies capable of meeting more stringent emissions standards,” Stigler said. “We are confident that all of our Final Tier 4/Stage IV solutions will provide the power, performance, ease of operation, fluid efficiency, reliability, durability and economical operating costs customers expect from
John Deere.”

With the use of SCR technology for Final Tier 4/Stage IV engines, total fluid economy becomes important, and John Deere is confident that its total fluid operating costs will maintain an industry-leading position. Total fluid economy takes into account both diesel fuel and diesel exhaust fluid (DEF). DEF consumption with John Deere Final Tier 4/Stage IV engines will be 1 to 3 percent of diesel fuel consumption depending on the application. With diesel fuel economy gains achieved through increased injection pressures and the optimized Integrated Emissions Control system, John Deere Final Tier 4/Stage IV engines are expected to improve upon the total fluid economy of Interim Tier 4/Stage III B engines. Low DEF consumption also means the DEF tank size can be smaller, minimizing space required on equipment. Other benefits of low DEF consumption include less on-site bulk storage requirements for customers and extended DEF filter service intervals.

“Our Interim Tier 4/Stage III B engines have been tested in many applications around the world and have established the benchmark for fluid economy,” Stigler said. “We’re confident that our Final Tier 4/Stage IV engines will continue to provide world-class fluid economy while delivering improved performance and higher machine productivity.”
John Deere has an established record of durability, accumulating over 22 million operating hours with various aftertreatment technologies.

Models and power ratings for the certified Final Tier 4/Stage IV engine lineup include:

• PowerTech EWX 2.9L: 36 kW – 55 kW (48 hp – 74 hp)
• PowerTech EWX 4.5L: 55 kW (74 hp)
• PowerTech PWL 4.5L: 63 kW – 104 kW (85 hp – 140 hp)
• PowerTech PSS 4.5L: 93 kW – 129 kW (125 hp – 173 hp)
• PowerTech PVS 6.8L: 104 kW to 187 kW (140 hp to 250 hp)
• PowerTech PSS 6.8L: 168 kW to 224 kW (225 hp to 300 hp)
• PowerTech PSS 9.0L: 187 kW to 317 kW (250 hp to 425 hp)
• PowerTech PSS 13.5L: 309 kW to 448 kW (414 hp to 600 hp)

The worldwide John Deere dealer network of over 4,000 service locations will be trained and prepared to fully support customers and their Final Tier 4/Stage IV engines.
