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

|Model||Working width (m)||Weight (kg)||Power requirement HP (min./max.)|
|Qualidisc Pro rigid||2.5 - 3.0 – 3.5 – 4.0||1467 - 2158||70/240|
|Qualidisc Pro fold||4.0 – 5.0 – 6.0||2718 - 3710||150/350|
|Qualidisc Pro trailed||4.0 – 5.0 – 6.0 – 7.0||3876 - 5365||150/400|
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 at the back 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.
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.
