Looking to expand its mechanical weed control line beyond the former Steketee products, Lemken has developed the Thulit, the firm’s first pressure harrow. It will be built at the new Crop Care factory in Dintelood in the Netherlands.
When developing the new harrow range, the engineers wanted to avoid using the familiar combination of springs and cables, like others do, to control the tine pressure across the peaks and troughs.
