During a press conference at the 2012 Commodity Classic, John Deere unveiled its final stage Tier 4 solution, the John Deere Integrated Emissions Control System.
Deere’s Barry Nelson said this is a major announcement that continues John Deere’s 175 years of innovation. “The past few years we have been spending millions and millions of dollars to develop new technology for the engines and the integrated technology we need in the vehicles to make everything work as a very productive package.”
John Deere Manager Worldwide Marketing Geoff Stigler gave an overview of how the technology was developed and why. “Engine technology is just one piece of the puzzle,” he said. “It’s really all about meeting customer expectations, delivering on the performance, durability, reliability and operating efficiency requirements.”
Geoff said the road to Final Tier 4 was a building block approach, starting with Tier 2 when the first electronic engines were implemented and moving through Interim Tier 4 which have been delivered for the past 18 months. “We have nearly 20,000 engines in the field right now that are Interim Tier 4 compliant,” he said. “We’ve been able to monitor those through our JD Link technology and have over 2 million customer hours on those engines already.”

Final Tier 4/Stage IV regulations for off-highway diesel engines begin as early as 2013 for engines 55 kW (74 hp) and below. Regulatory dates for engines 56 kW (75 hp) and above will be implemented in stages starting in 2014 and 2015, and require particulate matter (PM) levels established by Interim Tier 4/Stage III B regulations to be maintained while requiring an additional 80 percent reduction in nitrogen oxides (NOx) from previous regulations.
Consisting of an exhaust filter and SCR aftertreatment components that are optimized and fully integrated, the Integrated Emissions Control system will allow John Deere engines to utilize less diesel exhaust fluid (DEF) than alternative Interim Tier 4/Stage III B SCR technology solutions. Lower DEF consumption means DEF tank size can be smaller — minimizing the impact on vehicle applications, extending DEF filter service intervals and reducing operator involvement. Monitored and controlled by proprietary electronics within John Deere’s enhanced engine control unit (ECU), the Integrated Emissions Control system also provides outstanding fluid efficiency without sacrificing overall performance.

We’re talking about 300,000 cans of food here to replicate a full-sized S-Series combine in a field. It would be a world record. Kind of like what America’s farmers do every year – set new records in feeding the world.

I took the opportunity to interview Roberts, who is ranking member on the Senate Agriculture Committee, about what’s going on in Washington DC.
One of the highlights of the ceremony was the unveiling of the new building’s crowning centerpiece that stands at the main entrance – one of the original John Deere deer statues that were first made some time around the early 1900s. Regional controller Mike Snyder explained that an unknown number of the statues were commissioned by the son of John Deere in 1893 to be made by the W.H. Mullins Company of Salem, Ohio. “The statue is made out of hand stamped copper sheets, riveted and welded together and mounted on a steel frame,” he said, noting that Charles Deere saw the statue at the 1893 World’s Fair in Chicago and liked it so much he decided he wanted enough of them to be placed at every John Deere branch office and factory in the country. “Over the years, the importance faded and some were lost but recently company CEO Hans Becherer began a program to find and restore as many of them as possible.” The statue at the Olathe office is one of only 14 the company currently has.
