63-129 kW (84-173 hp)

Engine performance
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.

Reliability and uptime
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.

Increased auxiliary power

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 offers a low purchase price and integration cost, with performance benefits that contribute to overall customer value.

Compact engine package

The JD4 features a 20% to 25% reduction in package size and a more than 50 kg (110 lb) reduction in weight compared to the John Deere PWS or PWL 4.5L single-turbo engine. This compact design gives customers improved visibility and fuel efficiency.

Worldwide emissions compatibility

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.
