JD14 engine

The muscle to handle heavy draft disks and rippers, power-hungry air seeders and planters, and large transport loads like grain carts and slurry wagons. The durable design and heavy-duty components you can depend on when you need to get in and get out. A dual emission strategy is available for Australia and New Zealand; the 13.6L (827-cu in.) engine can be configured in either Final Tier 4 (FT4)/ Stage V or Tier 3/Stage IIIA compliant packages. You get real-world power with the purpose-built JD14 (13.6L/827-cu in.) engines from John Deere Power Systems, standard in the 291 to 471 engine kW (390 to 640 engine hp) 9 Series Tractors.

We developed our newest power plant from a clean sheet of paper, starting with stronger castings, beefier bearings, and more robust 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 for FT4 configurations, eliminated the diesel particulate filter (DPF) to boost to 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 (FT4 only).
• 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 tiresome 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.

It all adds up to:

• 14 percent more power and 11 percent more torque
• 3 percent lower fuel consumption
• 10 percent lighter
• 13 percent reduction in mean repair time, as well as savings in service costs over the life of the engine

Ultimate Visibility package at night

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.

*Convenience lights illuminate the corners of the cab for easier entry and exit.

** Starting with model year 2022, the Ultimate Visibility package is camera ready.

9R 640 equipped with HydraCushion suspension

Power that doesn’t get to the ground is power that’s being wasted. And a bumpy, hoppy ride can quickly drain an operator’s energy and productivity. So to help you get the most from every horse under the hood and every hour in the cab, 9R Tractors in wheeled configurations are available with the advanced, industry-exclusive HydraCushion suspension (HydraCushion is standard equipment on 477-kW [640-hp] models).

Along with a proven-reliable suspension design, HydraCushion suspension uses an advanced system of electronic sensors and hydraulic components to keep the chassis and front differential vertically centered, giving you more consistent contact with the ground while reducing road lope and smoothing out the bumps that cause a rough, tiring ride.

9RX in transport

You don’t have to compromise between pinpoint turns in the field and smooth, easy steering during transport – you can have it all with ActiveCommand Steering (ACS), available on all 9R and 9RX Tractors.

ACS lets you choose your steering ratio based on the task at hand. For precise headland maneuvers in the field, choose a tight 3.5 turns lock-to-lock. When you’re done in the field, ACS gives you a full five turns for smoother line-holding during road transport. Variable-effort resistance automatically changes with ground speed; you’ll notice a lighter touch during low-speed, in-field turns, and increased feedback at transport speeds for more comfortable, confident steering over the road. Plus, ACS works seamlessly with AutoTrac™ guidance systems and is compatible with wide and narrow section width tires as well as wide and narrow belts on 9RX models.

The end result? Reduced overall steering effort and fatigue, no drift and no backlash through the hand-wheel, all with the “connected” feel of a traditional steering column system
