The Lexion 700 Series rotary and straw walker models offer an award-winning threshing and separation design which boosts both harvest and fuel efficiency. For instance, the 563-hp, 360-bu. grain-tank Class X 770 along with other 700 Series rotary models feature the APS Hybrid System. In essence, this combines conventional threshing cylinder technology and a dual rotary separation system. It starts with the Accelerated Pre-Separation System (APS), which includes the accelerated pre-separation cylinder, a main threshing cylinder and an impeller.
According to the manufacturer, Claas, up to 30 per cent of grain is separated at the APS cylinder and sent directly on to the cleaning system. The remaining crop is fed into the main threshing cylinder at a gradual angle, covering the entire width of the cylinder at a constant thickness for higher grain quality. The impeller then divides and feeds the thrashed material into the RotoPlus dual rotary separation system.

The new 700 Series Lexion combines have redesigned cabs with seats which cushion, support, ventilate and keep the operator warm. Claas also includes its CEB IS display, tasked with total machine monitoring and control. It is coupled to an 8.4-inch colour display which monitors combine functions. This is enhanced by what Claas calls an intuitive, intelligent multifunction handle which controls header height, auto pilot, laser pilot, GPS steering, grain tank unloading, feeder house stop and reel operation.
The LEXION 670 walker combine features the walker separation system. Its impeller first spreads the crop mat across the entire width of the straw walker and then the Multi-Finger Separation System fluffs and agitates the straw, increasing grain separation in the six straw walkers, making it easier to separate the remaining grain from straw.
