On January 30, 2026, John Deere unveiled its model year 2027 combine lineup, introducing a major shift in approach: from optimizing individual features to focusing on whole-machine efficiency. The announcement, made during a media event in Austin, Texas, highlighted how the company is aiming to boost overall harvest productivity while lowering fuel consumption and improving grain quality.

"We've taken a step back and asked, ‘How do we add value to the entire harvest job?'" said Brady Alley, John Deere's combine marketing manager. He explained that the company's new vision includes smart automation tools, serviceable modular components, and hardware designed for broader, more precise farming systems.

Key updates include new modular concaves, remote-operated concave and separator grate covers, and a hydraulic folding ladder-all aimed at reducing downtime and simplifying in-field maintenance. Each machine also features a 550-bushel grain tank and a 35-foot unload auger built for 40-foot controlled traffic farming, streamlining harvesting operations for modern large-acre systems.

The tech upgrades go deeper, with significant improvements to John Deere's Predictive Ground Speed Automation software. For 2027, operators can now set throughput as a performance target, allowing the combine to automatically adjust speed based on real-time yield and green-crop sensing. Smart startup settings also provide crop-specific recommendations for header and combine adjustments, improving operator efficiency from the first pass.

John Deere has added six new crops-oats, lentils, sunflowers, triticale, rye, and peas-to its Harvest Settings Automation system, reflecting the growing diversity in U.S. cropping systems. "It's way easier to edit something that's on paper than it is to create something from scratch," said Alley. "These smart startup settings give our customers a solid baseline based on crop type and geography."

Alongside the combine updates, John Deere introduced the new CF 27 corn head, designed for 20-inch row spacing and optimized to pair with the DB90 54-row planter. The corn head features Auto Back-Shaft Speed, which syncs head operation with the combine's ground speed, and Auto Deck Plate Adjustment, which uses sensors to detect stalk diameter and adjust the deck plate spacing accordingly.

"We needed a corn head that matched the performance and precision of our 20-inch systems," said Alley. "The CF 27 delivers exactly that."

Together, these updates reflect John Deere's shift toward integrated machine performance, supporting large-scale operators who demand both precision and productivity. By focusing on seamless operation from field entry to grain storage, the 2027 combine lineup marks a significant step in John Deere's long-term ag tech strategy.
