The Knegt overtop cultivator is intended for cultivating soil with stones and tall grass. This overtop cultivator is characterized by the fact that it rotates in a different direction than the direction of travel of the tractor. In addition to making the soil ready for sowing, the soil also gets more air. Only the fine soil is allowed through and the large clods and stones can only leave the cultivator box under the bar rack. The Knegt overtop cultivator is equipped with a mesh roller as standard.
