The power harrow for maximum continuous loads and any cultivation methods

LEMKEN’s Zirkon 12 rotary harrow is designed for maximum continuous loads for both conventional and conservation tillage. The active tools of the Zirkon 12 produce an intensive mixing and crumbling effect to about 15 cm working depth and thus prepare an optimal seedbed in virtually any soil conditions. The intensity of cultivation can be precisely controlled via the forward travel speed, the PTO speed and the rotary harrow gearbox.

  • The welded gear trough made of thick-walled special steel ensures that all gears, shafts and bearings run easily and smoothly, which in turn is a guarantee for a long service life.
  • The standard DUAL-Shift gearbox allows the motor speed to be easily adjusted from 330 to 440 rotor revolutions per minute. The direction of tine rotation can additionally be easily switched from the grade to the drag position to adapt the implement to any conditions of operation.
  • The quick-change knife tines with a length of 340 mm and a thickness of 20 mm guarantee maximum durability. The quick-change system allows the tines to be easily changed without requiring tools.
  • With large working widths, the centrally positioned pendulum axles provide for optimum adaptation to surface contours.
  • The Zirkon 12 is suitable for both front-mounting and rear-mounting.
