High-capacity harvesting in corn and beans
Harvesting in corn
Designed for performance in coarse grain crops, the TriStream™ rotor and Dyna-Flo™ Plus cleaning shoe efficiently thresh and clean grain in tough harvesting conditions. The TriStream rotor helps maximize fuel efficiency with technology that reduces the force required to move material through the combine by as much as 20 percent. High capacity starts at the feeder house, where the S Series provides large areas of clearance for high volumes of crop to flow uninterrupted.
- TriStream rotor delivers performance – A slightly tapered front nose dramatically reduces the growling that often comes with thick crops and heavy rotor loads. Spiral vanes around the rotor guide the crop material through the feeding and threshing area, reducing hesitation and improving productivity. Meanwhile, rifling grooves on the elements allow the bullet-shaped rotors to move large volumes of crop material through the rotor more efficiently. Rifled elements grip crop material, providing a pulling action that helps even the crop flow, allowing the rotor to deliver better threshing performance.
- Dyna-Flo Plus delivers clean grain – Consider your capacity needs met. In fact, in shoe-limited conditions, you get 10 percent more capacity in corn than previous models, which equates to another 0.6 ha/hr (1.5 acre/hr). The key is uniform distribution and a unique two-stage pre-cleaning design. Four conveyor augers move material onto the shoe steadily and evenly, even on hillsides. A fixed front chaffer helps thin the crop mat; about 30 percent of the air goes to the front chaffer at high speed, allowing it to clean up to 40 percent of the free grain before it reaches the main chaffer. A huge rear chaffer and larger sieve (12 percent larger than previous models) are specially designed to handle the threshing and separating performance of the S7.
Spend more time harvesting in tough conditions
The faster you can get to – and into – your fields, the more productive you are. John Deere S7 Series Combines make it easy. Tracks help you get into the field sooner and finish faster. The ProDrive™ system lets you smoothly shift between two speed ranges (field and transport) with the push of a button; you’ll no longer have to stop to shift when going up or down hills or when you’re exiting a field.
- Get your harvest on track – Your ability to get into your fields sooner is easier than ever. Reach a road transport speed of almost 40 km/h (25 mph) with the John Deere tracks. The suspended track system provides a smoother ride with better ground following. This makes for more comfortable harvesting days and lets you finish faster. Available with 76.2- or 91.4-cm (30- or 36-in.) wide belts, these tracks deliver better ride quality and ground following, improved flotation, and less compaction. In addition, there’s no daily maintenance.
Harvester with tracks
- ProDrive ground drive system – This lets you switch between two infinitely variable speed ranges with the push of a button. Using the CommandARM™ armrest console, you can set the first range for typical harvesting speeds and the second for transport. This reduces your combine’s engine rpms during transport while still maintaining a productive ground speed, improving fuel economy. An electrohydraulic differential lock with a four-pinion differential delivers greater traction in muddy conditions.
In-cab adjustments with CommandARM console
- Two-speed, four-wheel drive (4WD) is perfect for demanding conditions – This lets you switch between torque ranges. In slow-speed mode, the high-torque rear assist is ideal for tough conditions. Use high-speed mode for low-torque performance and faster ground speeds.
Raise your capacity in tough small grains or rice
Harvesting in wheat
Truly tough conditions demand more than simple solutions. Rather than slightly improve performance in rice, canola, wheat, barley, oats, or other tough small grains, John Deere S7 Combines set new capacity standards with four crucial components: Active Concave Isolation, a high-performance feeder house, heavy-duty interrupter grates with integrated interrupters, and the variable-stream rotor. When you’re looking at a storm on the radar and you don’t have time to spare, you can run full throttle and still put your toughest crop into the machine without any issues.
- Better material handling – The industry-exclusive variable-stream rotor features a longer, more tapered front cone design that excels in wet, green rice or small grains where the straw is especially tough. The variable-stream rotor with adjustable top cover transport vanes is recommended for rice producers and those facing tough threshing conditions. The vane angle can be adjusted to reduce the stress on straw material as it flows around the rotor, increasing the quality of the straw while using less fuel. Along with the tough material handling capabilities of the variable-stream rotor configuration, the straw quality and length can be improved due to the electrically adjustable top cover transport vanes.
- Dyna-Flo™ Plus cleaning shoe provides more cleaning capacity – In shoe-limited conditions, you’ll see a 14 percent capacity boost in wheat and canola compared to previous John Deere designs, raising your productivity and improving grain quality. Simply put, this is a cleaning system that does it all.
- Harvest through the toughest conditions – Active Concave Isolation (only available on S7 800 and S7 900 Combines) has been improved by applying hydraulic pressure to better secure the concave, providing extra stability when harvesting really tough crops. This increases the machine capacity by 10 percent, so you can harvest outside the optimal harvest windrow or crop conditions when necessary.
- Better feeding in tough conditions – The S7 Combine feeder house design features an exclusive pivoting mid-frame design to provide the highest level of material handling and feeding capacity, especially in high-volume, tough crop conditions. The front feed drum provides you with 5.1 cm (2 in.) of additional movement for greater flexibility in challenging crop.
