In recent years, agricultural work has seen drastic change. Soil cultivation with GPS support and the analysis of weather data are now standard practice, human labour has largely been replaced with automation and the traditional farm has become an efficient agricultural enterprise. We, the end consumer, experience these changes indirectly as we enjoy the wide range of high-quality agricultural products available for us to buy at affordable prices.

Our muscle in the field

Whether for tractors, combine harvesters or forage harvesters, filters for agricultural machines operate under the toughest conditions and – particularly in harvest season – are in constant use. The challenges here are the large amounts of dust and organic particles, as well as the enormous mechanical loads. Filters of original equipment quality provide reliable protection for investment goods and contribute to smooth operation and long-term value retention. Expert maintenance is a key factor here.

Maintenance without the wait

In practice, this means that any spare parts required must be made available promptly and in original equipment quality via a seamless logistics chain. Furthermore, it is essential that the machine operator has first-rate, in-depth knowledge of the machinery as they are, in effect, carrying out the same work as a specialist workshop in the automotive industry would do; in this respect the agricultural company is also a repair workshop. If maintenance work is required, everything works in perfect harmony: the spare parts are either stocked by a specialist dealer or can be procured through their logistics concept at short notice anywhere in Europe; once the spare parts are received, the machine operator needs to be able to carry out the service professionally.

Specialists in their area

Our customer, the company Kramp, is one such dealer specialising in the agricultural sector that runs regular training events in its in-house academy to pass on the relevant specialist knowledge. This year, a number of trainer events were held in cooperation with the Chamber of Trade, each lasting several days. The key theme here was cooperation: this is one of our customer’s four core values and one of which we have first-hand experience. For us, cooperation means assisting our customers both with advice and practical support, which is why we decided to take an active role in these events. On offer were various talks and workshops on topics including engine technology, pneumatics, lighting technology and drive shafts among others.

MANN-FILTER protects investment goods

Under the heading ‘Filtration in the agricultural sector’, we reported on what is involved in the area of filtration and how our brand MANN-FILTER contributes to the reliable and cost-effective operation of agricultural machinery. By giving the training participants an active role, we really struck a chord with them: a hands-on demonstration of filter maintenance provided them with useful background information, and produced some ‘wow’ moments amongst the audience. One example of what they learnt was that you can’t just use any type of cyclone cell for preseparation when dealing with organic dust; agricultural machines might have different cyclone cells to those used in construction machines.

It quickly became clear that preseparation has something to do with a drop in pressure. This topic and its significance were a constant throughout the seminar, and we were able to draw parallels between the air filter and other engine components and look at how they influence each other while interacting. So it wasn’t long before we touched on the functional principle of the turbocharger and the working method of the closed crankcase ventilation. Indeed, there is a direct correlation between these components and the air filter. We also looked at the other filter types in connection with neighbouring engine components, which gave us a full and interesting overview of how they interact.

Of course, it is not possible to turn all participants into filtration specialists over the course of one morning but we did manage to give the participants a better grasp of filter quality and helped to differentiate this from other filter properties, such as the much-cited filter fineness. There was a particularly engaging discussion of why many filters have to be ‘relatively open’ and ‘absolutely must not be fine’. While some may have found this illogical at first, it was possible to explain it using practical examples such as hydraulic circuits and fuel systems.

Sowing and harvesting

We were particularly pleased with the reaction the trainer events received, with our efforts mentioned in various relevant magazines and agricultural technology portals.
