John Deere is rolling out a comprehensive package of updates across its T5/T6, S7 and X9 combine harvester series in Europe. The latest developments on the 2027 (MY27) model range focus on productivity, in-cab convenience, slope performance and advanced automation, thus achieving lower cost of harvest under increasingly diverse field conditions.
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 PGSA will also be capable of using an operator-defined crop throughput target as an additional automation setting. When enabled, PGSA 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.
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.
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.
Expanded sidehill options
For MY27, the S7 range offers four sidehill configurations. These 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 10.7 m 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
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 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 continues to evolve for MY27, expanding the number of compatible crops. New additions include oats, sunflower, triticale, rye, peas, lentils and rice, allowing automatic optimization across a wider range of harvesting conditions and regions.
