The threshing cylinder on the 5185 E has a 600 mm diameter for high inertia and performance. Eight counter-rotating threshing bars effectively separate the grain during the threshing process. Both the grain and straw are handled very gently and breakage is minimised.

With one of the largest concave areas in its power class, the 5185 E drives in the large harvest volumes in the shortest time. The different wire spacings within the concave are the main reason for this: While the wire spacing in the front area is narrow to ensure intensive threshing, the wider wire spacings in the rear part of the concave permit a higher separation capacity.

After the threshing unit, the straw is effectively fluffed up over 4.30 m long straw walkers with a 150 mm stroke. Four 250 mm high steps create a loose straw mat, which permits residual grain to be separated perfectly in the huge separation area. The closed straw walkers distribute the grain uniformly over the entire width of the preparation floor for efficient separation.

Front perfect, the rear, too: the front and rear concave openings can be adjusted independently. You can adapt the threshing unit to any possible harvesting conditions from the comfort of the cab.

There are two front segments available for the quick-change sectional concave: 14 mm wire spacing for grain harvesting and 24 mm for maize harvesting.

The so called active, open rear walls of the steps further improve residual separation.
