Electrohydraulic system offers clear comfort advantage
The LEMKEN range includes not only the Diamant 11, which has already received substantial praise in the profi agricultural journal, but also another monowheel semi-mounted plough, the Diamant 12, which was taken through its paces in supplementary field tests conducted in autumn 2013 and spring 2014. It is interesting that the critical question raised in the headline - "Electrohydraulics for more comfort only?" - was answered on a resoundingly positive note both in the article text and in the evaluation table. The Diamant 12 features a fully controlled version of the traction enhancement, which ensures that the freely adjustable system pressure is consistently maintained, even when driving over crests, and thus minimises slip. At the same time, pressure is taken off the traction enhancer when the plough is raised or when driving on the headlands, which results in optimum tractor stability on slopes.
Another detail that is often overlooked adds clear customer value: The Diamant 12 (without brake) is the only plough of its type that can be taken onto the road. Even with the 9-furrow version and automatic stone protection, the wheel load is a "mere" 2.8 tons - yet another benefit of controlled traction enhancement.
The authors concluded that, while many (including some profi editors) may believe that an electrohydraulic system is out of place in a plough, one could/should/must beg to differ!
The full report can be found in the September issue of the profi Journal.
