Working depth is quickly pre-set hydraulically without risk to the operator. Depth adjustment of the rear roller and levelling tines is fine-tuned using swing clips on the hydraulic cylinders. Access to the swing clips is easy and safe on both sides. The weight of the rear rollers is transferred to the disc harrow for reliable soil penetration.

Hydraulic folding enables convenient and trouble-free road transport at a width of 2.80 m. The disc harrows are folded in two halves to achieve a low transport height. The automatic transport interlocks are operated by hydraulically actuated lock pins.

A uniform surface finish with the best mixing performance meets farmer's and contractor's expectations in the field. To achieve this, PTTINGER has optimised the geometry, size, mounting angle and penetration angle of the discs. The result: Low drag resistance, perfect ground penetration, best crumbling and mixing effect.

Two solid forged carrier arms are welded to a very wide clamping bracket. This ensures that the discs always retain their position and angle. Even in heavy soil it is impossible for them to deviate to the side hard tyre tracks are broken up reliably.

The rugged scalloped discs made of special heat-treated steel have a diameter of 58 cm. Eight discs per metre of working width equate to a spacing of just 12.5 cm. The optimised interplay of ground penetration angle and mounting angle ensure perfect performance. The offset configuration of the aggressive discs mixes harvest residues effectively into the soil.

Proven over many years in the field, the maintenance-free NON STOP trip protection system features 40 mm thick rubber elements. The clamping brackets are mounted on a thick-walled box section frame. Four rubber elements between each wide clamping bracket and the box section provide the discs with high penetration power.

Fast operating speeds and working depths down to 12 cm mean the disc bearings have to withstand considerable stress. That is why PTTINGER has implemented high-quality bearings for an extended service life.

Ruggedness and reliability are guaranteed as a result and impacts are absorbed perfectly.

• The sealed, twin-race tapered bearings are completely maintenance-free.

• A labyrinth seal provides perfect protection for the bearing.

• A metal cover encapsulates the labyrinth seal for additional security.

• The bearings are fitted to the disc carrier arm by a stub axle.

• The nuts are protected by caps mounted on the same axle bolt.
