Rubin 12


Compact disc harrow with in-depth effect

With Rubin 12, LEMKEN introduces a compact disc harrow that enables deeper cultivation comparable to a tined cultivator up to a depth of 20 cm. The Rubin 12 is suitable both for stubble cultivation and for primary soil tillage, even under the heaviest soil conditions.

Intense crumbling

Two rows of serrated concave discs with a diameter of 736 mm let the Rubin 12 mix and crumble intensively.

Working without side force

The symmetrical arrangement of the discs in each row enables working without lateral pull, even at high driving speeds.

The slope is what counts

The angle of the discs of 20° to the soil to provide optimum penetration.

Inclined position & full coverage

The inclined position to the direction of travel by 14° and 16° enable cultivation over the whole width from a working depth of 7 cm.

Stubble cultivation without clogging

Specially curved and coiled legs ensure maximum clearance between the discs. This prevents clogging, along with the slight offset of the middle discs.

Perfect leveling

An impact harrow behind the first row of discs provides intensive mixing and crumbling, while a levelling harrow behind the second row ensures optimal soil distribution and perfect levelling.

Lift and transfer the weight

In the mounted version, the Rubin 12 can be equipped with a depth and transport wheel, which loads the front tractor axle when the implement is lifted. Here, a new semi-mounted system is used that requires no additional control unit.
