High-performance harvesting methods with 2-row elevator harvesters are of particular importance in many regions. Especially for these centre trailed harvesters GRIMME offers the KSA 75-2, as a perfectly matching 2-row haulm topper with lateral haulm discharge. The potato haulm is mechanically crushed with a large flail shaft and conveyed to the side of the ridges. The lateral discharge of the haulm significantly reduces the risk of blockages at the intake unit and increases the machine capacity accordingly. This applies in particular to modern potato varieties, which have an enormous amount of high, strong haulm to improve assimilation for an increased yield. A further advantage is the reduced load on the separation devices, which minimises harvest losses and increases separation quality.
