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

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 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.
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.
John Deere integrated solutions: a world of connected technology, right from the factory
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.

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.
