Cultivator KNRF 4.2 (6-row) - is designed for inter-row cultivation of row crops without fertilisation. The presence of a transport device allows the cultivator to be transported on public roads.

It is possible to use the cultivator for continuous cultivation with razor blades, as well as for hilling.

The parallelogram suspension of the working body sections has increased rigidity, which eliminates damage to crops and ensures copying of the soil relief. All units are mounted on rolling bearings. The atmospheric tyre of the copying wheel provides self-cleaning during operation.
