Highlights

Sturdy frame and reinforced headstock

  • Extremely sturdy - the Qualidisc is fitted with a frame well-proven with the Kverneland cultivator range.
  • Reinforced headstock and a frame size of 100 x 100 x 8 mm, the Qualidisc can be equipped with the heaviest roller.
  • The brackets of the roller are fixed at the front bar of the frame for a better weight transfer during road transport and also at higher driving speeds.
  • Due to the small distance between the disc sections, the Qualidisc requires reduced lifting capacity
  • The working depth is easily adjusted by spacers situated at the depth cylinders
  • The lateral deflectors are folded to keep the transport width in line with road traffic regulations

Maintenance-free bearings

  • Each angled arm is fitted with a large maintenance-free double ball bearing and 35 mm axle. This high-quality bearing is able to carry heavy radial and axial loads.
  • Special protection on the side of the arm is achieved by a special seal of 5 sealing lips and by the joint protecting the bearing.
  • On the other side the disc is protected against dust by an O-ring.
  • The disc hub is fixed onto the arm by a bolt and special washers that prevent any loosening. The bolt is protected against soil by its position inside the arm.

Perfect Cutting Quality

  • The upper part of the arm is fitted with special brackets to avoid any lateral movement: the cutting angle is fixed to ensure an optimum cutting quality even under the driest conditions.
  • The rear disc section operates offset to the front unit to provide optimum performance and trash incorporation
  • A rubber shock system adjusted to the size of the disc and working speed.
  • The maintenance free arms are mounted between rubber buffers to absorb any shock loads from contact with unforeseen obstacles.
  • A disc of large diameter (570mm) in order to achieve a perfect cutting quality even at a shallow working depth
  • This increase in diameter allows ease of operation in the highest volumes of vegetable residues.
  • The notched discs improve its penetration and rotation irrespective of any plant residues

  • Cage roller Ø 550mm
  • Coil roller Ø 500mm
  • Double cage roller Ø 400mm
  • Flexline roller Ø 585mm: grooving and heavy, for the re-compaction on light to medium soil.
