The Cracker-Disc roller (diameter: 550 mm) can be combined with rigid active soil tillage implements. Ideal on very heavy soils, it improves the structure and leaves a fine crumbled seedbed. The large 550 mm diameter steel packer rings ensure a good carrying ability and the optimum reconsolidation of the soil. The wave profile on the steel rings and the cutting knives between the steel rings provide the maximum crumbling effect, even on heavy soils.

The longitudinal bars integrated in the steel packer rings ensure a good self-driving effect and scrapers keep the gaps clean in between the steel packer rings – in this way, blockages are prevented.
