Lemken Rubin 9/400

Engineering Precision in Soil Cultivation

The Lemken Rubin 9/ short disc harrow is designed for high-speed operation with a focus on maximum soil-residue mixing. The core of the unit features 620 mm diameter scalloped discs, each mounted on an individual stand. This specific geometry ensures an unobstructed flow of organic matter, preventing clogging even when working through dense corn stalks or heavy crop residues.

The Mechanics of Effective Mixing

The structural advantage lies in the symmetric arrangement of the discs. Unlike rigid-frame implements, each disc here is mounted on a curved leg equipped with a spring-loaded overload protection system. In field conditions, this provides two critical operational benefits:

• Dynamic Adaptation: When hitting an obstacle, the spring mechanism triggers instantly, dampening shock loads and protecting the main frame.
• Intensive Soil Turnover: The disc angle is optimized for aggressive soil crumbling and mixing with residues at depths of 7 to 15 cm, significantly accelerating mineralization.

Structural Stability and Depth Control

The frame of the Lemken Rubin 9/ is engineered for heavy-duty tractor operations. Traction resistance is balanced across the width, ensuring the implement maintains consistent working depth even in compacted clay-loam soils. The integrated rear rollers don't just break up clods; they provide crucial reconsolidation, which is essential for moisture retention and capillary rise. It is a robust solution for farmers who demand precise control and predictable performance across every hectare.
