LEXION combines use a cylinder style threshing system with three cylinders.

The Accelerated Pre-Separation (APS) cylinder provides up to 30 percent threshing before the crop ever touches the main threshing cylinder. Grain threshed from the APS moves on a prep pan straight back to the cleaning system. The APS also helps feed the main threshing cylinder evenly and at a constant speed, increasing grain quality. The main threshing cylinder only threshes the tough crop. The third cylinder is referred to as the impeller; this feeds the Rotors. 

A LEXION combine also uses rotary separation. With two, smaller-diameter rotors in back, a LEXION combine generates more centrifugal force, translating to better separation and increased grain tank sample. This is why LEXION combines are referred to as "hybrids."

By utilizing both systems, LEXION sets a higher benchmark for grain quality and capacity.
