Lemken launch new compact disc harrow

Lemken has launched the Rubin 10 compact disc harrow with a number of essential upgrades including new disc arrangement giving directional stability, without lateral pull, and better fuel consumption. Available in widths of 2.5-7m, it will go into series production from 2019.

The three central discs have been offset so they work collision-free across the full working width at a line distance of 12.5cm. The discs engage across their full surfaces from a working depth of 7cm. An undercut maintains optimal penetration and boosts mixing efficiency.

The Rubin 10 features surface-hardened DuraMaxx discs with a diameter of 645mm as standard, giving 30% longer working life than that of conventional discs. New 30mm thick legs are more robust than in the previous range. An improved design incorporating multiple bends provides plenty of clearance to prevent blockages.

Each concave disc in the Rubin 10 is now equipped with overload protection with damped return to minimise frame loads. The overload protection pockets are welded to the frame to keep the discs perfectly on track.

An integrated harrow behind the first row of discs improves the crumbling effect and distributes soil and organic matter in the driving direction, while the rear impact and levelling harrow distributes the soil to form an even, level surface.

The mounted Rubin 10 version is available with a Uni wheel for lower lifting force requirements and reduced loads on the rear tractor axle. Load is applied to the mechanical wheel system as the implement is raised, and no additional spool valve is required. This also allows heavier rollers to be used to achieve better reconsolidation.

All folding versions feature hydraulic depth adjustment as standard. The semi-mounted compact disc harrows are available as options with depth control wheels, ensuring even working depths in variable soils and precise pass alignment along slopes.
