The JD14 (13.6L/827-cu in.) engine from John Deere Power Systems has the power to handle heavy draft disks and rippers, hydraulically demanding air seeders and planters, and large transport loads like grain carts and slurry wagons. With a durable design and heavy-duty components, you can depend on the Final Tier 4 (FT4)/Stage V compliant JD14 engine, standard in the 291 to 471 engine kW (390 to 640 engine hp) 9 Series Tractors.

We developed the JD14 from the ground up, starting with stronger castings and bearings and tougher internal components, all designed to meet the high demands of field operations. We replaced the fuel injectors with a high-pressure common rail (HPCR) fuel system and eliminated the diesel particulate filter (DPF) to boost fuel efficiency and lower operation and maintenance costs. Integrated coolant and oil passages, along with a new belt-driven water pump, eliminate potential leak points and allow for a less-crowded engine compartment, improving serviceability and reducing debris accumulation.

In redesigning the engine, we also gave it:

• Hydraulic valve lash adjusters to maintain valve-lash settings during engine operation, reduce valve train noise and wear, and allow for greater fuel efficiency.
• A hydraulic fan drive for improved cooling capacity with no required maintenance.
• A new integrated wiring harness design featuring a modular layout for reduced vibration, greater reliability, and easier service and diagnostics.
• A rear gear train that integrates fully into the cast-iron block, reducing engine noise and improving the durability of the crankshaft damper.
• Combination sensors where possible, meaning fewer sensors, connectors, and wires.
• A powerful engine brake that allows operators to use the engine to control tractor and implement speeds while transporting or traveling downhill, reducing wear on the drivetrain brake components.

Visibility is more than just lighting. It’s mirrors where you need them, shades for the blinding late-fall and early-spring sun, wipers to help keep all the glass clear, and integrated camera capability. The new 9 Series Tractors let you choose the visibility package that best suits your needs – Select, Premium, or Ultimate with 360-degree light-emitting diode (LED) lighting –so you and your operators can run with all-conditions confidence.

John Deere makes it easy for you to access an entire suite of connected applications, all designed to help you make the most of every seed, every hour, every gallon, and every bit of machine-related information.

Each 9 Series Tractor comes standard with the John Deere StarFire™ 6000 Integrated Receiver and Generation 4 CommandCenter™ display; there’s no need for setup, installation, or initial global positioning system (GPS) calibration. Integrated AutoTrac™ assisted steering gives you accurate, scalable guidance for low-stress operation in nearly any conditions and can improve field efficiency by 10 percent or more. The 9 Series Tractors also feature standard JDLink™ telematics and users can turn on connectivity in the John Deere Operations Center for anytime, anywhere access to critical machine and field information. And every tractor comes from the factory with John Deere Connected Support™, so you and your dealer can anticipate and address critical system needs.

From here? The sky’s the limit. Choose any of our operation-specific applications to help maximize efficiency and productivity during planting, tillage, or other field activities.
