Diamant 18, a heavy duty work plow

The Diamant line, one of the flagship series of the Lemken brand, is a range of self-propelled plows that recently saw the launch of a new model, the Diamant 18. Like all the other equipment in the range, the Diamant 18 plow is also suitable for surface or deep soil working, and can be equipped with a tracking roller for reconsolidating the soil. The latest addition to the Lemken range, designed to be paired with high-power tractors (up to 650 HP), features a robust 180/180/12.5 mm square-section frame and up to eight plowshares; features that make it suitable for the most demanding jobs. Especially on dry terrain, – the German company states in a technical note – the Diamant 18 stands out for its stability and ability to penetrate the soil (the reconfigured position of the wheels allows for the optimization of the extra load on the frame). One of the most significant design innovations of this model is the repositioning of the support wheel, which is now located behind the frame. This construction innovation means that the plow bodies sink into the ground and maintain a constant working depth set by the operator, while the new positioning of the tires lowers the center of gravity, thus reducing the rotation forces to which the plow is subjected and decreasing the stress on the rear suspension. As the Alpen-based company explains, this translates into greater protection of the components, greater stability of the tractor/plow combination, and smoother operation. Other pluses of the Diamant 18 model include the steering system for the transport wheel. The hydraulic steering – as indicated in the Lemken note – automatically adapts the turning angle during maneuvering and in combination with the 90° steering angle on the headstock allows for tighter curve radii.
