免维护耙片轴承。采用6道密封，5个唇口迷宫式密封附加1个轴承密封，可有效防止异物进入，保证轴承的长时间使用。
弹指耙能够梳理土壤，使细碎土壤颗粒平整地停留在表层，形成有利于作物生长的种床。
高硬度的圆锥型耙片，可保证耙片在任何直径条件下入土角度不变，达到最佳的耙茬效果。小缺口耙片保证良好的切割入土性能，得到平整的底层。
耙片固定架采用压槽设计，保证耙片不侧移，始终保持稳定的切割角度。保护装置采用高强度橡胶条。

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
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
- 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.
- Actiring roller Ø 560mm: active with the adjustable knives, ensuring a good mixture of soil and straw and consolidation.
- Actipack roller Ø 560mm: heavier, for clod crushing and very firm recompaction of the soil. Adapted also for heavy and sticky soil conditions.
