Straw walker technology

Get it all. Residual grain separation.

The APS threshing system works so efficiently that only 10% of the grains remain for the residual grain separation system of the LEXION to recover. The APS system separates 90% of the grain from the straw.

The even flow of straw on the open-bottomed straw walkers with an extreme gradient angle ensures that practically all the grain is separated from the straw.

Effective straw walker technology.

A separate returns pan sends the grains on their way to the grain pan.  Residual grain separation is accomplished over a total length of 4400 mm across four straw walker steps. The LEXION 670/ 660/650/640 models are equipped with six straw walkers and the LEXION 630/620 models with five. Center and side extensions are available. Even large volumes of straw are transported rapidly and loosely.

The MSS loosens things up.

Thorough loosening the straw mass is critical for high separation efficiency, particularly under difficult field conditions such as wet straw or green growth. This is why all LEXION straw walker combines are equipped with the multifinger separation system (MSS), a drum with controlled tines positioned over the straw walkers. It ensures effective residual grain separation under all conditions.

MSS increases output.

MSS actively fluffs the crop with multiple controlled tines which dig into the straw. The tines reach in to the mat of straw from above and aerate it whilst simultaneously speeding it up and effecting active control of the crop flow. The available length of the straw walkers is used more effectively, whilst the structure and quality of the straw is optimised. The operation speed of the tines can be adapted to differing harvest conditions.
