While tractor manufacturers like us are constantly measuring our performance in the field, there continues to be a need for third-party, unbiased data agricultural producers can rely on. In the United States, that need is met by the Nebraska Tractor Test Laboratory.
According to the Lab’s web site:
“The University of Nebraska Tractor Test Laboratory is the officially designated tractor testing station for the United States and tests tractors according to the codes of the Organization for Economic Co-operation and Development (OECD) . Twenty-nine countries adhere to the tractor test codes (including non-OECD members: China, India, the Russian Federation, and Serbia), with active tractor test stations in approximately 25 of those countries. The OECD codes require that tractors be tested in the country of manufacture. Reciprocity agreements with the codes require that once an OECD test report is officially approved, it must be accepted by all participating countries.”
The Nebraska Test Lab is a neutral organization that does not endorse any tractor or manufacturer. It is housed at the University of Nebraska in Lincoln, affiliated with OECD, administered through the Nebraska Tractor Test Board and funded by U.S. tractor manufacturers. According to Roger Hoy, director of the Nebraska Tractor Test Laboratory, “Our mission is to provide useful, unbiased data in the form of test reports on all tractors that we test.”
The Nebraska Tractor Tests first began in 1920 with legislation initiated by Nebraska farmer W.F. Crozier and State Senator Charles Warner. Crozier had purchased a tractor that did not live up to its advertised claims, so he wished to protect fellow farmers from such misleading claims. In 1980, the original lab building was declared an American Society of Agricultural Engineers historic landmark.
Preliminary Nebraska Tractor Test results reported by Case IH indicate that Tier4A-compliant, 2011 model year Case IH Steiger and Magnum tractors utilizing Selective Catalytic Reduction (SCR) technology have set industry records for fuel-efficient power.
Those preliminary results are awaiting final signature from the Nebraska Tractor Test Board of Engineers and will then be posted for FREE download at tractortestlab.unl.edu. We expect this posting to be finalized shortly.
If you’ve heard about the new 2011 Tier 4A engine emissions requirements, you’ve probably heard mention of Diesel Exhaust Fluid aka DEF. But, you might not know a whole lot about it. Below, we’ll shed some light on DEF.
What is DEF and when will I need it?
DEF – a stable, non-toxic solution made of synthetic urea and deionized water – is a key ingredient for the Selective Catalytic Reduction (SCR) exhaust after-treatment process being utilized in model year 2011 and beyond Case IH high horsepower tractors. In combination with proven Case IH engines, this technology will improve engine power and responsiveness, fuel economy, and overall durability for Case IH Steiger®, Magnum™, and Puma™ tractors, while helping them meet 2011 EPA emissions regulations.
Both SCR and CEGR exhaust after-treatment systems create a huge inconvenience for farmers.
FACT: For the SCR system to break down nitrogen oxide, a DEF tank was added. Other than keeping the tank full, you don’t need to think much about it. The tank contains a temperature sensor and heating element, which keeps the DEF at the optimum temperature whether you’re in a warmer cold weather climate. It also includes a fluid level indicator that will alert you when fluid levels are low, just like your diesel fuel level. A good rule of thumb is to fill your DEF tank at every other diesel fuel fill-up. Bottom line, if you know how to pump fuel and change oil filters, these tasks aren’t much different and are just as accessible.
Each month, I’ll introduce a Case IH expert to be our Be Ready guest blogger. I’ve invited Leo Bose as our first expert blogger, to discuss Tier 4A engine technology, facts or fiction. Leo is the training manager for Case IH and is responsible for developing the North American training strategy. He has been with Case IH for more than 16 years, serving in various positions, including combine marketing manager, training specialist on harvesting and planting equipment, training specialist on tractors and product support specialist on under-100 horsepower tractors. He also hails from a farm background!
Be sure to ask questions and we’ll help get the information you need to make informed decisions about Tier 4A.
From their invention more than a century ago, today’s diesel engines have evolved into more powerful and fuel-efficient engines. While that’s a good thing, their high emissions are bad for the environment.
By now, you’ve probably heard about the new federal regulations mandating cleaner, more efficient engines beginning in 2011. Maybe you’ve even heard some acronyms like SCR and CEGR and wondered what it means to you.
Listen up, class is in session!
Tier 4 emissions regulation was created to crack down on air pollutants – primarily particulate matter, which we know as soot, or unburned fuel, and nitrogen oxides (NOx) emitted as a by-product of an engine’s internal combustion process. Doing this requires the addition of an exhaust after-treatment system, such as Cooled Exhaust Gas Regeneration (CEGR) or Selective Catalytic Reduction (SCR). (more…)
