Amazone is now offering a knife roller as a front tool for its Cirrus 6003-2 folding trailed cultivator drill.
The central enclosed roller core, with its chevron knife arrangement, is a unique feature. It provides additional crumbling on cloddy soils and ensures the intensive shredding of surface crop residues as catch crops and tall stubbles are chopped at right angles to the direction of travel.
A reduction in the number of working passes is another advantage of the knife roller when used in combination with the Cirrus 6003-2. This preserves soil structure, conserves essential soil moisture and cuts costs and working time.
Seedbed preparation for cereals after sunflowers involves cutting tall crop residues at right angles with the knife roller and aligning them in the longitudinal direction with the following Minimum TillDisc cutting discs. The seed placement accuracy is thereby considerably increased since the sowing coulters aren’t affected by the crop residues.
Even shredding and incorporation of maize stubble helps promote good field hygiene after the maize harvest. Use of the knife roller with the Cirrus 6003-2 saves an additional run with a mulcher, roller or disc harrow for cultivating pre-working stubbles.
The knife roller improves the effectiveness of the drill when sowing directly into a standing catch crop by intensively cultivating the catch crop and incorporating it into the soil if necessary.
The knife roller is characterised by its extreme robustness. In particular, the sturdy roller bearing mounts and the knives made from Boron steel ensure a long service life. The knife fixings are recessed into the round tube on the roller. The central, enclosed core of the roller is extremely insensitive to stones and dirt contamination.
The knife roller is absolutely maintenance-free as a result of the spherical roller bearings and the face seals. Reversible blades, sharpened on both sides, halve the wear costs.
A distinctive feature of the knife roller is the chevron blade arrangement that prevents lateral pull. The contour following is provided via the individual knife segments. This means that the knives operate evenly over the entire working width, even on undulating ground.
