John Deere offers a variety of track widths and track spacings to fit the needs of your operation. The narrow undercarriage is great for row crop applications and can be ordered with track spacings of 203.2 cm (80 in.), 223.5 cm (88 in.), or 304.8 cm (120 in.). The wide undercarriage is ideal for tillage and seeding applications and is available with 223.5-cm (88-in.) or 304.8-cm (120-in.) track spacing.

9RX Tractors equipped with 76.2-cm (30-in.) and 91.4-cm (36-in.) tracks can be equipped with industry-exclusive, factory-installed track spacing set at 304.8-cm (120-in).

9RX Tractors equipped with 304.8-cm (120-in.) track spacing provide increased stability, allow producers to operate on 304.8-cm (120-in.) centers for controlled traffic farming, and provide improved track-to-frame clearance for better access to the undercarriage for serviceability and material cleanout. John Deere is the first and only tractor manufacturer to offer a 304.8-cm (120-in.) track spacing option on four-track tractors with 76.2-cm (30-in.) and 91.4-cm (36-in.) tracks up to 462.3 kW (620 hp).

9RX with 91.4 cm (18 in.) tracks and 304.8-cm (120-in.) track spacing

9RX Tractors with 304.8-cm (120-in.) track spacing increase space between the undercarriage and chassis to provide more space for performing daily and routine maintenance tasks.

Performing daily maintenance tasks

Selective control valves (SCVs) on a 9R Tractor

Of course, the 9 Series has the hydraulic muscle you need to push, pull, lift, and power your most demanding implements. But thanks to a range of enhancements to the hydraulic system, these tractors can provide that power at lower engine speeds, saving you fuel while still giving your implements the capacity they need. Regardless of model or configuration, the new 9 Series hydraulic system gives you:

• An increase of almost 40 percent in charge pump capacity, from 54-cc to 75-cc, to help maintain a higher flow at lower engine speeds
• A new swash plate angle sensor to monitor hydraulic flow and pressure and adjust engine speed to meet demand
• An integrated hydraulic pump, filter, and priority valve for fewer and shorter lines, reduced pressure loss, fewer flow restrictions, and an extra level of reliability

And if you depend on implements that need continuous hydraulic power, the 9 Series Tractors are available with Intelligent Power Management (IPM). Using dual pumps and advanced sensor and control technology, IPM provides additional engine and hydraulic power for high-demand applications like air seeding up and over hills or through thick, tough soil.

Add in single and dual pump options and a flexible number rear SCVs, and you can configure a powerful, fuel-efficient hydraulic system to meet the demands of your specific operation without paying for capacity you don’t need.

9RX Tractor

When you’re trying to get a field planted before weather moves in, there’s no time to hit a scheduled maintenance interval or get smacked with an unexpected repair. That’s why we designed the 9 Series for maximum reliability and less in-season maintenance.

To start, we simplified as many systems as possible, using components common to other tractor lines and minimizing potential downtime due to parts availability. Then we eliminated as many potential pain points as possible through changes in the cooling, aftertreatment, and diagnostic systems, including:

• Replacing the fan drive system with a maintenance-free hydraulic fan drive
• Streamlining aftertreatment with a single-canister inline system that’s simpler and features fewer parts
• Improving uptime by adding better descriptions to diagnostic codes and offering predictive diagnostics through John Deere Expert Alerts
• A front-left service panel for easier access to engine oil check and fill points;
• Offering a 500-hour oil change interval on the John Deere JD14 (13.6L/827-cu in.) Final Tier 4 (FT4) engine when using approved John Deere oil and filter.

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

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.

Ultimate Comfort and Convenience package (shown on 8R Tractor)

When you’re spending dozens of hours per week in the cab, a comfortable operating environment isn’t just an option – the right features, in the right places, let you and your operators work at your best, dawn to dusk and beyond.

The 7, 8, and 9 Series Tractors offer three Comfort and Convenience packages to fit your needs: Select, Premium, and Ultimate. But regardless of which package you choose, you’ll still get the John Deere CommandARM™ console that puts critical controls within easy reach. You’ll get all the storage space you need for drinks, meals, and other stowable items. And you’ll have plenty of outlets to keep your electronics powered.

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. All in a Final Tier 4 (FT4) and Stage V compliant package. 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 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.
• 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 and an estimated $8,308 savings in service costs over the life of the engine

13.5L (824-cu in.) engine compared to JD14 (13.6L/827-cu in.) engine

NOTE: The PowerTech™ 13.6L (827-cu in.) engine has been renamed the JD14.
