Kverneland Qualidisc Pro

Qualidisc Pro: Compact disc harrow from 2.5 to 7 meter

Compact disc harrow: from 2.5 to 7 meter

Stubble cultivation is of major importance within conservation tillage: It incorporates weeds and volunteer cereal seeds into the soil with an intensive mixing and promotes their germination for a more efficient subsequent treatment.

The even incorporation of the straw presents a key factor for seed germination. Therefore, Kverneland has designed the Qualidisc Pro to comply with these requirements, but also to offer the farmer a versatile machine which is ready for shallow as well as for deeper cultivation.

There are three different models:

-  Qualidisc Pro rigid mounted

-  Qualidisc Pro F as folding mounted model

-  Qualidisc Pro T as semi-mounted model

The Advantages:

  • Compact and sturdy
  • Good penetration and cutting quality
  • Simple adjustment
  • Perfect cutting angle
  • Long lasting discs
  • Maintenance-free bearings
  • 2 years of warranty

Qualidisc Pro: Sturdy frame

  • Extremely sturdy - the Qualidisc Pro is fitted with a frame well-proven with the Kverneland cultivator range.
  • Due to the strong headstock and a frame size of 100 x 100 x 8 mm, the Qualidisc Pro 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 Pro 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

Due to the aggressive discs and the considerable weight (up to 150 kg/disc), the Qualidisc Pro and the Qualidisc Farmer ensure an excellent working quality even under dry conditions.

The ground is completely cut, the stubble broken apart and correctly mixed on the surface for a good emergence of weeds and volunteer cereal seeds.

A constant cutting angle
Whatever the diameter of the disc, the cutting angle is always constant due to its conical design.

Long lasting discs
Discs of 6mm thickness and  Ø600mm for the Qualidisc Pro.
Discs of 5mm thickness and  Ø520mm for the Qualidisc Farmer.

The discs are given a special heat treatment for a long durability and strength. Thus the machine's longevity is increased and the maintenance costs reduced.

Big notched discs
Kverneland proposes discs with big notches to enhance the rotation in fluffy soil and for a better self-cleaning of the disc with more than 20% of clay. Small notches are kept to maintain the very good cutting quality.

Rear rollers

A large choice of rollers

According to the soil specifications, the consolidation required, the mixing of the soil and straw, the surface of the soil requested and the lifting capacity available, Kverneland offers a choice of rear rollers.

  • Cage roller Ø 550mm - 90kg/m
  • Double cage roller Ø 400mm - 160kg/m
    (available on mounted rigid and mounted folding models)
  • Actiring roller Ø 540mm - 160kg/m: active with the adjustable knives, ensuring a good mixture of soil and straw and consolidation.
  • Actipack roller Ø 560mm - 205kg/m: heavier, for clod crushing and very firm recompaction of the soil. Adapted also for heavy and sticky soil conditions.
  • Actiflex roller Ø 580mm - 160kg/m: intensive mixing effect combined with a good recompaction makes this roller the ideal tool for best volunteer's regrowth.
  • Actipress Twin Ø 565mm - 220kg/m without soil:
    (available on mounted rigid and mounted folding models)
    u-profile for high carrying/rolling capacity in light soils. Clod breaking also in heavy conditions. High and homogenous consolidation.
    Weight when full of soil: 250kg/m
