In the demanding world of modern agriculture, unpredictable weather and challenging crop conditions are often the norm. Farmers need equipment that not only performs but excels when the going gets tough. The John Deere Combine, specifically the S7 series, rises to this challenge, offering innovative solutions designed to maintain peak harvesting performance even when conditions are far from ideal. Instead of simply making incremental improvements, the John Deere S7 Combines are engineered to set new benchmarks for harvesting capacity across a range of difficult crops, from rice and canola to wheat, barley, and oats. This superior performance is achieved through four key advancements: Active Concave Isolation, a high-performance feeder house, robust interrupter grates with integrated interrupters, and the variable-stream rotor. When time is of the essence and adverse weather looms, these features allow you to push your John Deere combine to its limits, processing even the heaviest crops without hesitation.

Enhanced Material Handling with the Variable-Stream Rotor: A standout feature of the John Deere combine S7 series is its industry-exclusive variable-stream rotor. This innovative component boasts a longer, more tapered front cone, specifically designed to excel in wet, green rice or small grains where straw is particularly tough to manage. For producers dealing with rice or consistently challenging threshing conditions, the variable-stream rotor with adjustable top cover transport vanes is highly recommended. The adjustable vane angle offers a crucial advantage: it reduces stress on straw as it moves around the rotor. This not only improves straw quality but also enhances fuel efficiency. Furthermore, the electrically adjustable top cover transport vanes contribute to superior straw quality and length management alongside the rotor’s inherent tough material handling capabilities.

Dyna-Flo™ Plus Cleaning Shoe for Unmatched Capacity: The Dyna-Flo™ Plus cleaning shoe significantly elevates the cleaning capacity of the John Deere combine. In situations where cleaning shoe capacity is the limiting factor, operators will experience a remarkable 14 percent increase in capacity when harvesting wheat and canola, compared to previous John Deere designs. This directly translates to increased productivity and improved grain quality. The Dyna-Flo™ Plus cleaning shoe is engineered to be a comprehensive cleaning solution, handling a wide range of crop types and conditions with ease.

Consistent Harvesting in the Toughest Environments with Active Concave Isolation: The Active Concave Isolation system, available on S7 800 and S7 900 John Deere combine models, has been further refined to provide even greater stability and performance in extreme conditions. By applying hydraulic pressure to securely lock the concave, this system enhances stability when harvesting exceptionally tough crops. This improvement boosts machine capacity by up to 10 percent, enabling you to extend your harvesting window and work effectively even when crop or weather conditions are less than optimal.
-
Superior Feeding in Demanding Crops with Advanced Feeder House Design: The feeder house design on the S7 John Deere combine is engineered for exceptional material handling, particularly in high-volume, challenging crop conditions. It features an exclusive pivoting mid-frame design that maximizes feeding capacity. The front feed drum provides an additional 5.1 cm (2 inches) of movement, offering greater flexibility when dealing with difficult or uneven crop flow. This ensures consistent and efficient feeding of material into the combine, even under the most demanding harvesting scenarios.
