Here’s What Missouri and Illinois Farmers Should Know About John Deere 2027 Combine Updates

7/1/2026

The stakes are high during harvest season for Midwest farmers. With more pressure to do more in less time, farmers need equipment that can carry the weight and make the most of every pass. John Deere has announced a wide range of updates and enhancements to its model year 2027 X9 and S7 combines and front-end equipment, built around the latest predictive and automated technologies. Operators can expect expanded automation across more crop types, increased capacity and handling for the X9, better performance on challenging terrain, and stronger connectivity. For farmers working across corn, soybeans, and other row crops, these updates can provide significant benefits to your operation.

Automation for More Crops

Harvest Settings Automation Expands

New Harvest Settings Automation updates enable Midwest farmers to get in the field as quickly as possible. The expansion automatically sets concave clearance, fan speed, rotor speed, sieve clearance, and chaffer clearance based on the combine model, crop type, and geolocation. Previously available for corn, soybeans, wheat, barley, canola, and rice, the 2027 model adds lentils, peas, rye, triticale, oats, and sunflowers. Good news for diversified operations that need to switch between crops quickly.

Predictive Ground Speed Automation (PGSA)

PGSA controls ground speed based on crop height and biomass measurements, using data from pre-harvest satellite imagery or real-time cab-mounted cameras. Operators can set throughput targets, enabling the system to match optimal ground speed with harvesting performance to keep grain losses within acceptable limits. For model year 2027, PGSA and Harvest Settings Automation are more closely integrated, allowing both systems to respond to one another and better achieve producers' desired outcomes. Less operator intervention required, which is a meaningful advantage for Midwest farmers running with less experienced help during peak harvest.

Increased Capacity and Handling (X9 Series)

HDX 50 Draper Header

The X9 will feature a new HDX 50 header for MY27 with a working width of 50 ft (15.2 m). The larger header significantly increases feeding capacity and supports the X9's high throughput capability while maintaining smoother crop flow at high harvesting speeds. More acres covered per pass means more flexibility when racing against fall weather windows.

Grain Tank Capacity

Fewer stops, more time harvesting. The new 550-bushel grain tank option allows for longer time between unloads, more capacity when opening fields, and includes heavy-duty final drives.

Auto Unload / New Unloading Auger

The new 35 ft (10.7 m) unloading auger on the X9 creates an additional 4 ft (1.22 m) of clearance between the header and unloading auger. This allows for wider header use or controlled traffic farming, unloading on-the-go on a 12-meter system, keeping the combine moving during the passes that count.

Upgrades for Challenging Terrain

Active Slope Adjustment

Rolling terrain across Missouri and Illinois can disrupt grain flow and increase losses. Active Slope Adjustment (ASA) addresses this automatically, without operator input. Now available as a full specification option across all S7 combines, ASA uses terrain data from the StarFire receiver to automatically adjust active belt speed and level crop flow to the cleaning shoe on side slopes.

TRU THRESH Concaves

MY27 introduces TRU THRESH concaves for the X9, with an updated design that improves modularity and simplifies crop changeovers, including the ability to control concave and separator covers from the cabin. With this new design, operators can make faster crop changeovers and remote adjustments meaning less stopping, less wear, and a cleaner cab environment.

Connectivity and Precision

JDLink Boost Receiver

Both the X9 and S7 combines can come equipped with a JDLink Boost receiver from the factory, providing satellite connectivity in areas with limited or no mobile coverage. JDLink Boost also allows machines to transmit data in real time to and from the John Deere Operations Center, supporting advanced automation and giving farmers the information they need to better manage their fleets.

Factory-Precut Openings (HarvestLab Install Ready)

All model year 2027 X9 combines feature factory pre-cut openings in the clean grain elevator for HarvestLab mounting, making installation straightforward. This enables yield monitoring and grain quality measurement, feeding data directly into the Operations Center for fleet and field management decisions.

Next Steps for Midwest Farmers

More automation, more capacity, better terrain performance, and stronger connectivity make the 2027 X9 and S7 well-suited for Midwest row crop operations.
