John Deere introduces model year 2027 combine updates across T5/T6, S7 and X9 ranges

Productivity, automation and in-cab convenience enhanced across John Deere’s walker, rotary and high-capacity combine ranges

For model year 2027 (MY27), John Deere is rolling out a comprehensive package of updates across its T5/T6, S7 and X9 combine harvester series. The latest developments focus on productivity, in-cab convenience, slope performance and advanced automation, supporting operators in achieving a lower cost of harvest under increasingly diverse field conditions.

T5 and T6: proven automation and new in-cab adjustments

Predictive Ground Speed Automation now available on T5/T6

Predictive Ground Speed Automation (PGSA) is being introduced to the T5 and T6 combines for MY27, following its successful launch on the S7 in MY25. The system controls the combine’s ground speed based on crop height and biomass measurements taken pre-harvest from satellite scans and from on-the-go measurements made by cab-mounted cameras, such as down crops or dense weed patches. Machines equipped with Predictive Ground Speed Automation will also be capable of using an operator-defined crop throughput target as an additional automation setting. When enabled, Predictive Ground Speed Automation with throughput will intelligently link ground speed with grain quality to help optimize harvesting performance and allow more dynamic speed adjustments to keep grain loss within acceptable limits. Jonathan Edwards, John Deere Go To Market Manager, said: “This is technology that no other brand can offer, and we have seen how much of an impact it can have on productivity during one of the busiest times of the year.”

Remote adjustment of booster bar and separator grates
MY27 brings new remote adjustment capabilities to the T5 and T6 threshing and separation system. The booster bar and separator grates can now be adjusted directly from the cab, allowing operators to react immediately to changing crop conditions without stopping or leaving the machine. This
improves productivity while keeping the cab clean and reducing downtime.

New unloading auger options

Two new unloading augers expand the T5/T6 range. A 6.10 m rigid auger improves compatibility with wider headers, while a 7.30 m foldable auger for T5 models addresses markets with stricter road homologation requirements and provides a good match for 9.1 m platforms.

S7: improved performance on slopes

Active Slope Adjustment
Active Slope Adjustment (ASA) is now available as a full specification option across all S7 combines. Using terrain data from the StarFire™ receiver, the
system automatically adjusts the active belt speed to level crop flow to the cleaning shoe on side slopes. This results in more even material distribution
and effectively doubles cleaning shoe performance without compromising grain quality or capacity.
Expanded sidehill options
For MY27, the S7 range offers four sidehill configurations, allowing customers to select the right solution for their operating conditions. Options include the Sidehill Kit, Active Slope Adjustment and HillMaster™, providing solutions for slopes from gentle undulations to more demanding hillside terrain while maintaining grain cleanliness and reducing losses.

X9: higher capacity and new feeding options

Larger HDX header
The X9 combine range gains a new HDX 50 header for MY27. With a working width of 50 ft (15.2 m), the new header significantly increases feeding
capacity, supporting the high throughput capability of the X9 and improving operator comfort by maintaining smoother crop flow at high harvesting speeds.
New grain handling options
New grain handling options further enhance the X9’s productivity in high yielding crops. A larger 19,400-litre grain tank option is now available, increasing productivity in the field with fewer unloading stops. Also, a new 10.7m unloading auger supports controlled traffic farming and improves unloading efficiency in wide working widths.
New threshing and separation options
MY27 also introduces new threshing and separation configurations for the X9, including TRU THRESH™ concaves. The updated design improves modularity and simplifies crop changeovers, for instance by controlling concave and separator covers from the cabin.
Technology updates across the combine portfolio
New technology package configurations
For MY27, John Deere is introducing revised technology package structures across all combine series. The available Select, Premium and Ultimate
packages differ by machine family, allowing customers to tailor automation and guidance functionality to their operational needs while clearly
differentiating capability levels between T5/T6, S7 and X9 combines.
Auto unload: a step towards autonomy
Auto unload is now available on S7 and X9 combines. The system automatically guides the tractor and trailer during unloading, ensuring consistent grain
distribution while reducing operator workload and stress. Live fill monitoring provides real-time feedback, allowing the combine operator to focus on crop
throughput even while unloading on the move.
Harvest Settings Automation with broader crop compatibility
Harvest Settings Automation continues to evolve for MY27, expanding the number of compatible crops. New additions include oats, sunflower, triticale,
rye, peas, lentils and rice, allowing automatic optimisation across a wider range of harvesting conditions and regions. “With the model year 2027 updates, we are making our combines more intuitive, more connected and more adaptable to harvesting conditions in the field,” concluded Jonathan Edwards, Go-to-Market Manager Combines for Europe. “By combining proven mechanical upgrades with smarter automation across all series, we are helping customers harvest more efficiently, with greater confidence and lower cost of operation.”
