4WD and Track Tractors
The new 9 Series Tractors alleviate timing challenges, offering more power, more ballasting options, and more precision than ever before. No matter your terrain, no matter your conditions, these tractors give you the strength and power you need to pull heavier, wider implements with ease. And with integrated precision ag technology, you can manage your biggest fields in the tightest timeframes to achieve the bottom-line results you’re after.
PowerTech™ 13.6L (827-cu in.) engine: real world usability, not just power on paper
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 13.6L (827-cu in.) engines from John Deere Power Systems, standard in the 291 to 440 engine kW (390 to 590 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
- 27 percent reduction in mean repair time and an estimated $8,308 savings in service costs over the life of the engine
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 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.
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.
In the field or on the road: adjust steering ratio on-the-go with ActiveCommand Steering (ACS™)
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

Accessories and Attachments
Front Axle Support Kit, DR - 9330RWBRE10145
Front frame and axle support kits provide additional support to the front frame and axle joint when the tractor is used in applications that put high torque and high vertical loads on the front end of the machine. This includes front-mounted liquid tanks and front 3-point hitches.
A front frame support kit is required on all 9RX Tractors with front-mounted liquid tanks or a front 3-point hitch. This kit enables operators to utilize the 9RX Tractors for supplemental crop nutrition application or for utilizing a rear 3-point hitch mounted sprayer. The front frame supports are standard on all 9RX Scraper Tractors.
Mounting of dozer blades
The mounting of dozer blades is approved on 9R and 9RX Tractors with 762-mm and 914-mm (30-in. and 36-in.) tracks. The mounting of dozer blades is not approved on 9RT and 9RX Tractors with 457-mm and 610-mm (18-in. and 24-in.) tracks.
- For all 9R and 9RX Tractors with 762-mm and 914-mm (30-in. and 36-in.) tracks, additional frame supports supplied by the dozer manufacturer are required.
- Follow manufacturer guidelines for mounting dozer blade components to the frame of the tractor.

ISO Cab Implement CAN bus Adapter - 9330RWRE322780
The model year 2020 and newer large tractors (with updated cab) have a low-profile, offset StarFire receiver integrated into the roof shell. However, there is a mounting bracket solution to add a StarFire 3000 (with deluxe shroud) or StarFire 6000 Receiver. This bracket connects to the center of the front roof near the wiper motor for an exceptional fit with a clean look. The 12-pin wiring harness on both the StarFire 3000 and StarFire 6000 are compatible with the base cab electrical connector.
