2022 John Deere 5E Series 5100E

• John Deere PowerTech™ Diesel Engine with FT4 emissions compliance

• Cab or open operator station available

• Standard 12F/12R PowrReverser™ Transmission and MFWD

• 540/540 Economy PTO

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 18.6 kW (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 5E 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.

• Key components of the emissions system include:

• 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 nitrogen oxide (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. Since the exhaust filter removes particulate matter instead of the engine, the engine is left free to do what it is designed to do – deliver all of the power, torque, plus transient response needed at the exact moment needed.

• DEF

• DEF is an ISO 22241 standard aqueous urea solution consisting of 32.5 percent urea and has a freezing point of -11° C (12° F). A DEF tank keeps the operator in the field longer even when the temperatures drop below freezing. The DEF tank header is integrated with a temperature sensor and plumbed engine coolant lines are used to promote thawing and prevent freezing in the tank during operation.

• DEF tank

• Mounted near the DEF tank, the engine control unit (ECU)-controlled supply module draws diesel exhaust fluid from the storage tank and provides a pressurized flow to the dosing module. When the ignition key is off, the supply module pump will reverse direction to return any accumulated fluid back to the tank. The supply module is also fitted with a replaceable filter to prevent contaminants from entering the dosing lines. Both the supply module and dosing lines are electrically heated and controlled by the ECU to determine when diesel exhaust fluid dosing can begin.

• The dosing module is cooled by engine coolant and used to inject DEF at a pressure of 900 kPa (130 psi) into the decomposition tube. A harness is connected to the dosing valve that relays the needed DEF to inject based upon the amount of NOx exiting the DOC measured from the NOx tube sensor.

• The decomposition tube is the internal mixing device used to circulate DEF with engine exhaust prior to entering the SCR/AOC after-treatment device.

• SCR

• To reduce the NOx, DEF, or urea, is injected into the exhaust stream. When the exhaust gases combine with the DEF in the SCR catalyst, the NOx is broken down into nitrogen and water vapor.
