Compact disc harrows being extremely versatile tillage implements become even more effective and flexible when combined with knife rollers. The TERRADISC T with working widths of up to 6 m can be equipped with a knife roller as a pre-tool to cover an even greater range of applications. This opens up a wide range of applications from seedbed preparation, stubble cultivation of cereals, oil seed rape, sunflowers and maize, to the incorporation of cover crops. The additional shredding effect eliminates the need for prior cultivation and breaking up of the stubble, saving time and resources. Likewise, it promotes the incorporation of organic matter as well as its microbial decomposition. Harmful organisms find it more difficult to reside there to survive the winter, so their growth in numbers is prevented. If the knife roller is not required on a particular job, it can be folded away completely so that it no longer contacts the soil.
The knives on the leading knife roller are arranged in a spiral. This ensures that it rotates smoothly since it is in constant contact with the ground to produce a uniform load on the cutting edge. The roller diameter of 350 mm ensures a high speed of rotation. These features deliver consistent chopping quality and high cutting intensity, resulting in a powerful shredding effect. Due to the knife roller's consistently high cutting resistance, it operates reliably even on hard soils. The depth of the front tool is adjusted hydraulically, so it can react quickly to different site conditions.
The knife roller can be retrofitted to existing TERRADISC T models with a working width of 4 to 6 m from the year of manufacture 2018. All the mounting points required for this are already on the machines, which means that no modifications to the TERRADISC are necessary.
