Lemken Rubin 9/500 KUA

Optimized Disc Geometry

The core of the Lemken Rubin 9/500 KUA lies in its 620 mm serrated concave discs. Engineered for high-speed operation (up to 15 km/h), the 6 mm thick steel provides exceptional durability against rock impact and abrasive soil conditions. The disc angle ensures uniform soil inversion across the entire working width, effectively incorporating crop residue into the topsoil profile without creating uneven ridges.

Maintenance-Free Bearing Units

Downtime is the enemy of productivity. The Rubin 9/500 KUA addresses this with high-performance angular contact ball bearings protected by specialized cassette seals. These units are completely sealed against dust, water, and debris, eliminating the need for periodic lubrication. This engineering choice ensures long-term reliability even under the heavy duty cycles of a commercial farm.

Symmetrical Disc Arrangement

A distinctive feature of the Rubin series is the symmetrical arrangement of discs in two rows. This design effectively cancels out lateral forces, ensuring the implement tracks perfectly behind the tractor without drifting. This stability is a significant advantage when using GPS-guided systems, as it prevents overlapping passes and keeps the load on the tractor hitch consistent, ultimately reducing fuel consumption.

Hydraulic Control and Consolidation

Depth control is managed via a hydraulic system, allowing the operator to adjust the working depth on-the-go from the tractor cab. The integrated rear roller system serves dual purposes: it provides precise depth control and ensures optimal soil reconsolidation. This firming effect is crucial for restoring capillary action in the soil, which helps trigger uniform weed germination and prepares a firm, level seedbed.
