Heavy-duty disc harrow

These disc harrows are used specifically in vineyards. When the soil is cultivated for vineyards, a disc harrow that can be flexibly adjusted in width is required. This is because the tool must be designed for tracks of different widths. For this working width adjustment and adaptation to different row widths, the two tool rows are hydraulically shifted against each other. Due to the tough field of application, which is characterised above all by a high level of dirt and dust, the individual disc rows require a particularly efficient sliding bearing system. Specifically, the company was looking for a bearing that was maintenance-free, precise, space-saving, very resilient, easy to produce and durable under the tough operating conditions.

As the sliding bearing had to be maintenance-free, precise, space-saving, durable and very resilient, tribo-tape liners were installed directly in the orifices of the machine frame. tribo-tape liner made of iglidur high-performance plastics is suitable for lining tribologically stressed surfaces and shapes, for optimising transport tasks, for machine beds, as edge protection etc. It can be simply glued to surfaces that slide against each other. This protects them during their movement and saves energy at the same time.
The drylin shafts, on which the respective row of discs is guided and fastened, run in the guidance using a liner. The shafts, which can be made of aluminium, steel or stainless steel, are characterised in particular by their high corrosion resistance and load-bearing capacity.
