ROTO PLUS

The even feed of the APS creates ideal conditions for the separation of the remaining grain with ROTO PLUS. The principle behind ROTO PLUS is simple but extremely effective. The impeller of the APS threshing unit divides the straw into two flows of material and feeds them to the two counter-rotating, high performance rotors.

The rotor speed can be continually adjusted with ease from the operator’s seat with the CEBIS dial in the LEXION 760–740 models, anywhere from 350 to 1050 rpm regardless of the threshing drum speed.  This allows quick adjustment of the rotation speed to different crops as well as harvesting and straw conditions, making it easy to achieve the best work rates with the combine.

These are excentrically mounted and generate extremely high centrifugal forces which separate the last remaining grains from the straw.  With a diameter of 445 mm and a length of 4200 in each case, the LEXION offers an enormous separation area. The mixture of grain, straw and chaff first reaches the preparation floor through the returns pan before passing over the straw walker steps to the sieve pan.  This significantly reduces the load on the sieve pan.

Conveniently adjustable rotor flaps.

All LEXION models have electronically controlled shutters to enable adjustment of the rotor separation area. The HOTKEY dial allows stepwise reduction of the open separation area of the rotary sieves quickly and easily from the comfort of the cab.
