Rubin 12

Compact disc harrow with deep impact

With the Rubin 12, LEMKEN’s range of compact disc harrows includes an implement that can operate at the same 20 cm working depth as a cultivator. The Rubin 12 is therefore suitable both for stubble cultivation and for primary soil tillage, even in very heavy soil conditions.

  • Two rows of serrated concave discs with a diameter of 736 mm produce intensive mixing and crumbling.
  • The symmetrical arrangement of the discs in each row enables working without lateral pull, even at high driving speeds.
  • The 20° angle of the discs to the soil and the 16° angle to the direction of travel ensure optimum penetration and enable cultivation across the full width from a working depth of 7 cm.
  • The legs are specially curved and coiled and thus provide maximum clearance between the discs. This prevents blockages, along with the slight offset of the middle discs.
  • High speeds of travel at reduced slip result in lower fuel consumption and a higher acreage performance.
  • An impact harrow behind the first row of discs produces intensive mixing and crumbling, while a levelling harrow behind the second row distributes and levels the soil optimally.
  • In the mounted version, the Rubin 12 can be equipped with a Uni wheel, which transfers loads to the front axle when the implement is raised. This version includes a novel semi-mounting system that does not require an additional control unit.
