The new models (arriving in early October) in the 50-60 horsepower range are equipped with Mitsubishi common rail, DOC engines Brock explains. “None of our engines require diesel exhaust fluid (DEF) to meet EPA standards, but some models will be equipped with DPF,” he adds.
Do John Deere tractors require DEF?
PowerTech Interim Tier 4/Stage III B engines meet emissions regulations without using diesel exhaust fluid (DEF). John Deere provides an optimized solution using the right combination of emissions-reduction components to maximize performance while meeting regulations.
Do tractors use def fluid?
For 2014, diesel exhaust fluid (DEF) is going to be the norm for high-horsepower diesel engines,” says Luke Van Wyk, of Thunder Creek Equipment. “That means the pickups you drive, the semis you drive, the school buses your kids ride on, your tractors, your construction equipment – it’s all going to use DEF now.
Do compact tractors require DEF?
Premium Member. The current crop of Tier 4 compliant engines in the large frame compact utility tractors do not require DEF fluid. They have an exhaust burn off every 50 hrs or so to lower the soot levels.
What year did DEF start on tractor?
When Commercial Fuel Services Started Including DEF
Come 2008, the EPA mandated that all three-quarter-ton and larger trucks had diesel particulate filters installed.
Does sunlight hurt DEF?
DEF should not be stored in direct sunlight. … The quality of DEF also is not affected if the fluid freezes. When stored under optimal conditions — between 12°F and 86°F — DEF has a shelf life of up to two years. If stored in warmer temperatures, shelf life decreases.
Why do diesel engines need DEF?
DEF, also known as AdBlue or Blue DEF, is an elixir that’s necessary to make sure that what exits a diesel vehicle’s tailpipe is as sweet as an Alpine breeze. … Those two compounds then react with oxygen and detrimental nitrogen oxides inside the vehicle’s selective catalytic reduction (SCR) catalyst.
Does a John Deere 5075e use DEF?
Regardless, these engines are EPA Final Tier 4 (FT4) compliant through a diesel oxidization catalyst (DOC) and diesel particulate filter (DPF) system. Additions of a diesel exhaust fluid (DEF) are not required, saving the need for that second fluid to be on hand.
What is a Tier 3 tractor?
Tier 3 is the shorthand term for national vehicle emissions and fuel standards that will help us make big strides towards cleaner, healthier air. They are designed to reduce the soot, smog and other types of dangerous pollution that come from the tailpipes of our cars and trucks.
Do Tier 4 engines use DEF?
Tier 4 Final regulations called for a drastic cut in NOx levels. In most engines this was more than EGR alone could handle. The solution was to install a new exhaust aftertreatment system called selective catalytic reduction, or SCR. … The urea/water solution is commonly referred to as diesel exhaust fluid, or DEF.
