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.
