JD4

John Deere's next generation engines are simple to integrate, easy to service, and share many common maintenance parts. New to the John Deere engine lineup, the JD4 provides up to 129 kW (173 hp) of power. It features a rear gear train that offers customers higher PTO power. The engine also has an extended single-turbo range and provides 700 Nm (516 lb-ft) of maximum torque for improved high-load capacity and productivity. The JD4 offers a more reliable diesel exhaust fluid (DEF) delivery system. The engine also features extended fluid service intervals of 750 hours (1,000 hours possible), reducing maintenance costs for customers. Hydraulic lash adjusters (HLA) reduce the overall service requirements of the engine by eliminating valve lash maintenance. The JD4 engine offers up to two auxiliary drive pads, providing three times more available auxiliary power. This additional power allows flexibility and enables off-boarding for electrification and hybrid applications. The JD4 will be compatible with EU Stage III A – Stage V emissions levels through common interfaces. The Tier 3/Stage III A engine is low-NOx-ready with external cooled exhaust gas recirculation (EGR). The JD4 engine will also be compliant with U.S. EPA Final Tier 4 and EU Stage V with no EGR. The JD4 can be used with renewable diesel fuel and biodiesel blends. | John Deere's next generation engines are simple to integrate, easy to service, and share many common maintenance parts. John Deere power range extended! The JD18 extends the power range of the John Deere engine lineup to 677 kW (908 hp). Uptime-focused controls. Improved John Deere model-based controls offer better diagnostic capabilities, enabling future prognostics and the ability to target the source of engine performance issues. Designed for extreme durability. The JD18 features a bedplate design, providing structural benefits for rugged applications. Heavy-duty oversized components, steel pistons, and wet-type cylinder liners provide long engine life. The JD18 engine was designed with ease of service and repair in mind. Hydraulic lash adjusters offer a maintenance-free valve train, eliminating the need to reset lash. The JD18 features new combustion technology which allows John Deere to offer an engine in the 522 – 677 kW (700 – 908 hp) power range without aftertreatment. Without the need for DEF, the customer has one less fluid to manage. The high-pressure common-rail (HPCR) fuel system allows the engine to deliver optimized fluid consumption. The JD18 is compatible with renewable diesel fuel and biodiesel blends. The new combustion technology offers a simplified air system, with fixed and wastegate turbos, allowing the engine to meet emissions requirements without applying aftertreatment. This feature provides simplified engine integration and a compact package size. It features a rear gear train for excellent direct power and quiet operation. With options for up to two rear auxiliary drives, the JD18 produces a total of 902 Nm (665 lb-ft) maximum torque.
