• TRISTREAM™ ROTOR DESIGNED FOR COARSE GRAINS AND EASY THRESHING SMALL GRAINS: The TriStream rotor is unique to John Deere because it features a slightly tapered design in the threshing area for best-in-class grain quality while dramatically reducing the growling that often comes with heavy rotor loads. The TriStream rotor is recommended for producers who harvest mainly coarse grains along with easy threshing small grains. The spiral vanes surrounding the rotor guide the crop material through the threshing and separating area in a pull and release action to improve performance. This John Deere S700 Combine feature will generate less power consumption. Feature benefits: TriStream rotor technology reduces the force required to move material through the combine by as much as 20 percent, maximizing fuel efficiency. The rifling grooves on the threshing elements allow the bullet-shaped rotor to move material more efficiently maximizing crop threshing performance and grain quality. Heavy-duty vanes on the top covers propel the crop smoothly rearward through the length of the rotor ensuring all the threshed grain is separated. Functionality: Fifteen cast-constructed threshing elements provide superior material handling with excellent grain quality. The elements spiral around the rotor to control material flow. In some harvesting environments, the dense-pack configuration (nine additional threshing elements) may be necessary. Conical top covers allow for smooth material movement within the threshing and separating area. The top covers have a radius larger than the rotor, allowing the material to expand as it travels along the top of the rotor. This design uses the pull and release action of crop material, aiding in the threshing and separating to reduce power consumption.
