John Deere S790 Combine Price

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.

DynaFlo 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 S Series.
