ROTOTILLER KR

The chisel rotor

This chisel is ideal for soils with few stones. It has an exceptionally long service life. The chisels have brazed carbide tips and show virtually no wear. It is possible that these brazed chisel tips may chip off upon contact with very hard stones. In that case, the individual chisel should be replaced. However, this rarely happens. Therefore, a tine rotor should be used on “stone-rich” soils.

The mulch rotor

The mulch rotor operates primarily near the surface and ensures thorough shredding. Its mulching blades thoroughly shred and break down crop residues and cover crops, distributing the plant material evenly across the entire working width. With a maximum soil penetration of 2 to 3 cm, it preserves the soil structure and creates ideal conditions for rapid decomposition and active soil life.

The Tine Rotor

The tines are the tool of choice for stony soils. The special arrangement and shape of the tines ensure a piercing penetration without smearing. The tine strikes the stone vertically from above and either pushes it deep into the soil or shatters it. The disadvantage of the tine rotor is that the tines wear out over time. The more abrasive the soils, the faster they wear. And when that happens, the entire set of tines must be replaced.

Incorporation of crop residues

The KR neatly incorporates crop residues into the topsoil. Straw, cover crops, and plant residues are evenly distributed and mixed into the top 5–8 cm—ideal for rapid decomposition and humus formation.

Distribution is uniform across the entire working width, without any material being left behind or smeared. This creates ideal conditions for the next crop.

Sheet-Metal Roller

The trailing roller ensures soil reconsolidation and provides the necessary soil contact. DUTZI offers two roller variants:

The sheet-metal wheel roller is the more modern option. It is clog-free and can therefore be used even in wet conditions and on heavy soils.

Tine Packer Roller

The tooth packer roller is the more traditional type of roller, used, for example, in grassland or for specialized applications.

Can be used in combination with a seed drill

Any standard seed drill can be mounted on the KR. This allows the seed to be deposited directly into the prepared, crumbly soil structure. Crumbling, seeding, and reconsolidation—all in a single pass. Ideally, this can be combined with an FL at the front or with the TL shares directly in front of the rotor. This results in four work steps in a single pass.

This combination saves time, reduces the number of passes, and creates optimal germination conditions.

Versatile Applications

The KR is versatile:

On its own without coulters: secondary tillage, shallow crumbling, incorporation of cover crops

With TL shares or delta coulters: Primary soil cultivation with integrated Non-destructive deep-acting loosening (7–8 cm wide tools, as with the FL/HL) or by completely lifting and breaking up the compaction layer and incorporating significantly more material in a much more intensive manner: Working depth of the rotor with delta coulters: approx. 13–18 cm. Working depth of the rotor without Delta shares and with or without TL shares: approx. 5–8 cm.

In combination with the FL front subsoiler: OnePass soil cultivation with deep-acting loosening + crumbling + seeding + reconsolidation.

This modularity makes the KR the centerpiece of an adaptable soil cultivation system.
