With a maximum engine power of 830 hp, the Model Year 2025 John Deere 9RX four-track tractor is the company’s most powerful yet.
The 2025 9RX is a ground-up redesign of Deere’s 9RX series for its higher horsepower capabilities to achieve lower operating costs per acre, says Michael Porter, large tractors go-to market manager for John Deere.
With increased performance, the 9RX series enables farmers to eliminate passes, reducing soil compaction, and increasing productivity by 100 acres each day compared with previous models, Porter says. This is based on John Deere’s internal testing, comparing the 2023 9RX 640 tractor pulling a 2680H high-performance disk at 11.9 mph with the new 9RX top-of-the-line 830 tractor pulling the same tool at 13.4 mph, both at maximum power for eight hours a day at 4 inches deep in cornstalks.

Deere offers the 9RX series in three models: the 710, 770, and 830; each number correlates with the tractor’s rated horsepower. The tractors are built with in-line six, 6-cylinder JD18 engines, and 515-gallon fuel tanks. The JD18 is a single-fluid engine (strictly diesel fuel) requiring no diesel exhaust fluid (DEF). Deere estimates this can save a farmer up to 800 gallons of DEF per year.
The 9RX series uses the e21, 21-speed transmission with Efficiency Manager. Farmers select a traveling speed, and the transmission shifts and manages RPMs to maintain the speed. Porter says the transmission is quick to accelerate, for a smooth and responsive ride.
An optional triple pump gives the 9RX series a hydraulic flow up to 168 gallons per minute. For implements with high hydraulic needs, Deere can build the engine with optional Intelligent Power Management, adding a 40-hp bump. The 830 can achieve up to 3,123 pound-feet of torque at 1,400 RPM.
The 9RX series has a category 5 drawbar, with a maximum vertical load of 19,000 pounds.
The high power means the tractors can pull double the cart load of previous models, while going 1 mph faster on average, Porter says. This can help reduce refilling time, translating to more time in the field.
The new series has a base weight of 74,000 pounds, with a maximum ballast of 84,000 pounds. John Deere has forgone traditional suitcase-style weights, traded out for forklift-ready mono weights to expedite adding or removing the ballast.

Handling
These new four-track 9RX tractors have a 15.2-foot wheelbase, and a 22.3-foot turning radius from the rear axle centerline. The series uses Camso Ag 3500 tracks at 30 inches wide, with 88 inches of tread spacing. Optional Camso Ag 6500 tracks are available at 36 inches wide, with 120 inches of tread spacing.
Cab experience

The 9RX series is built with the new CommandView IV Plus cab, with 15% more floor space compared with previous models, and 20% more visibility on the right side, thanks to the removal of the wheel well.
The new cab suspension system has three degrees of freedom, allowing the cab to pivot independent of the rest of the tractor; the passive air seat provides a smoother ride. The seat in the Select cab package swivels 8° to the left and 40° to the right, while Premium and Ultimate package seats swivel 25° to the left and 40° to the right. Other amenities include a new footrest peg, extra storage for tools, and a cooling box for food and drinks.
Buyers can select from three radio packages, with options including AM/FM radio, auxiliary input jack, USB audio and video inputs, SXM satellite radio, Apple Airplay and Android Auto compatibility, speaker system, Bluetooth microphone, and more. Additionally, farmers can choose from three lighting visibility packages to meet their operational needs.

Technology
The 2025 9RX series employs the same built-in technology as Deere’s model year 2024 tractors. This includes an in-cab G5 Plus display, integrated StarFire 7500 receiver, JDLink modem connectivity, and autonomy-ready features.
“The autonomous-ready package offers all the hardware, software, and safety features that we know today will be required for autonomous operation in the future,” Porter says. “This allows the machine to easily convert to a fully autonomous tractor.”
