5E 3-Cylinder Engine
Overview
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.
5E 3-Cylinder models are equipped with powerful, reliable engine with no regen required while still meet the U.S. Environmental Protection Agency (EPA) Final Tier 4 (FT4) exhaust emissions regulations. The John Deere PowerTech™ 3029 EWR engine utilizes a diesel oxidation catalyst (DOC) and cooled exhaust gas recirculation (EGR) aftertreatment system – with no DEF fluid, no DPF, and no regen required, you can focus on completing your jobs while your tractor keeps providing the power you need.
- Provide excellent torque and fuel efficiency
- See over the hood with compact aftertreatment design
- Outstanding performance and durability

Several defining features on 5 Series tractors maximize the performance and reliability of the emissions package. A completely shielded DOC/DPF not only protects essential components from damage, it 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
Shielded for protection
Diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and cooled exhaust gas recirculation (EGR) Deere has chosen to utilize an exhaust filter (DOC) and/or diesel particulate filter (DPF) 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 or no DEF for 3-cylinder models. The result is improved total fluid economy (diesel and DEF). Some applications also reduce NOx using cooled exhaust gas recirculation (EGR) that allows a controlled amount of exhaust gas to be returned to the engine leading to lower combustion temperature for a cleaner, more efficient exhaust.
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 ofthe power, torque, plus transient response needed at the exact moment needed.
Wastegate Turbocharger
Wastegate turbochargers are designed to develop more airflow at lower engine speeds to improve low-speed torque. The wastegate control device bleeds off a portion of the exhaust flow at higher engine speeds. Wastegate turbos deliver improved transient response and higher peak torque without compromising engine envelope size. They also provide the lowest installed cost across a given power range.
