Perfectly aligned seedbed creates favorable conditions for uniform high-quality sowing, amicable shoots and, consequently, to higher yields. To solve this problem and developed a tough and active harrows Kverneland series M, H and S. here are some examples that have managed to improve the engineers in the new generation of these machines.

Frame with high strength and reliability at a reduced weight

In the new generation of active boron designers managed to increase the strength of the supporting frame, at the same time significantly reducing the weight of the whole structure of the gun. For example, the series S has 15% less weight than the model-predecessor.

Series M, H and S vary in size, but regardless of it all they are resistant to wear and tear. New sturdy mounting stand, which is the same on all models, delivers outstanding stability and long service life.

Gregor Cottonsedge, engineer R & d Department in the factory Kverneland Group in Zoisite (Germany), explains: "We have considered all the most aggressive scenarios, such as deep processing when rotating, the combination of with multiple-row seeders and stress tests in a stone pit to make all the models of the active boron as strong as possible".

Different teeth for optimal penetration into the soil

In the basic configuration, all models are equipped with standard teeth or can as an option be equipped with the teeth with a carbide coating to minimize wear and, consequently, the equipment downtime. Additional active teeth ensure optimum penetration in hard soil or stubble, and are available in lots H and S.

Responding to increasing customer demands for efficiency, the system of fast replacement of the teeth without the use of tools became available on all models. The rotor shaft and the holder teeth into the series H and S consist of two parts for easy maintenance and long service life even in stony soils.

Spiral arrangement of teeth

Four rotors per meter and spiral tooth pattern to reduce peak loads on the drivetrain resulting in a more smooth running and less fuel consumption. Range of packer rollers adapts to various soil types.

All active Kverneland harrows with seeders combined manufacturer. And thanks to the quick release coupling you can use the active harrow also independently.
