2026 John Deere AG 9R 490

More power and precision than ever for your toughest jobs

390 to 830 HP

Your work windows are tight—no matter the time of year. Whether tilling, planting, seeding, applying nutrients or transporting, starting earlier and running later may seem like the only solution. And the larger your operation, the faster those windows close.

The 9 Series Tractors give you options to alleviate timing challenges, offering more power, more ballasting options, and more precision. Our higher HP 9RX models (710, 770, and 830) can seed with twice the cart load in the hills and go 1 mph (1.6 kmh) faster while doing it compared to our previous 9RX models.

The 9 Series Tractors give you the strength and power you need to pull heavier, wider implements with ease. You can manage your biggest fields in the tightest timeframes to achieve the results you’re after.

Tractor

• Engine HP1: 539 Max / 490 Rated
• Fully integrated precision ag technology
• e18™ PowerShift Transmission
• Multiple cab and visibility packages

Features May Include: 

Improved Selection Control Valve (SCV) configurations

• The 9-series tractor plumbing is designed for max flow so there will be no restrictions in the system making it fast, easy, and cost effective if there is a need to switch between 1.3 cm (0.5 in.) and 1.9 cm (0.75 in.) couplers. Making the change between SCV coupler size will require a new housing and dust protection shield compared to a new SCV slice.

NOTE: Up to six SCVs can be factory installed. 9 Series Tractors can add SCV 7 and SCV 8 as  field-installed attachments. See Aftermarket kits for details.

JD14 (13.6L/827-cu in.) engine: real world usability, not just power on paper

• 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.

9 Series Visibility packages let you run with confidence, dawn until dusk

• 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 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.

• Rear window tint provides 10 percent light transmissibility (standard glass provides 70 percent light transmissibility)

Put more power to the ground, more comfortably, with the industry-exclusive 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.

Increase productivity with John Deere integrated solutions

Your needs and success are the focus of John Deere. John Deere makes it easy for you to benefit from having a connected tractor in your operation.

The technology and connectivity in John Deere tractors allow you to optimize productivity, increase uptime, and boost profits with machine information from any device, anywhere.

A range of hydraulic options give you the power and flexibility to take on your toughest applications

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.

The new 9 Series: Easy to run, easy to maintain

• 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.
