2021 John Deere 5090E

Description

2021 John Deere 5E Series 5090E Features may include: Environmental Protection Agency (EPA) Final Tier 4 (FT4) compliant engines with maximum fluid efficiency The U.S. EPA and Environment Canada requires all off-road diesel engines with 25 hp or more to meet stringent FT4 emissions regulations. John Deere uses the most efficient and cost effective solution for the tractor package to meet emissions requirements at each horsepower level. The 5M delivers a hassle-free emissions solution that allows faster work speeds and operation with ease. The engine powering the 5E is EPA-certified Tier Level 4. This is achieved through a combination of a diesel oxidation catalyst (DOC) and a selective catalyst reduction (SCR) using diesel exhaust fluid (DEF, or urea). Several defining features on the 5E maximize the performance and reliability of the emissions package. A completely shielded DOC/SCR not only protects essential components from damage but also keeps out dirt and debris. The well-packaged and tightly organized circulation system means there is more room to work around the tractor. DOC Deere has chosen to utilize an exhaust filter (DOC) to reduce particulate material so the engine can operate at a level which produces less NOx. With less NOx created, it requires less DEF to treat. The result is improved total fluid economy (diesel and DEF). The engine is programmed to aggressively respond to changes in power needs, which can temporarily increase particulate matter
