Secondary separation

The APS threshing system works so efficiently that the residual grain separation system in the AVERO requires fewer straw walkers than you'd expect. Thanks to APS, 90% of the grain is already separated from the straw. Four straw walkers with four steps take care of the remaining 10%. The AVERO processes as much as a comparable machine with five straw walkers without APS, but has the compact dimensions of a machine with four straw walkers. This has a noticeable economic impact.

The AVERO 160 also delivers above-average performance for its size: the classic CLAAS threshing unit works perfectly in combination with the four straw walkers.

The four straw walkers of the AVERO have been completely redesigned and adapted to the high-performance APS threshing system. Residual grain separation is accomplished over a total length of 3,900 mm across four straw walker steps. Centre and side extensions available. Even large volumes of straw are transported rapidly and loosely.

In addition, the straw undergoes intensive separation with controlled agitator tines. Agitator tines located above each straw walker dig deep into the straw, loosening and fluffing it to ensure a rapid straw flow and a thin layer of straw for the last grains to escape and effectively increase separation efficiency.
