The John Deere deep grooved roller packer is specially designed for models with a 4.3m grip. Levels the surface of the soil, crushing plant debris, loosening the soil and breaking up clods and breasts. Thanks to a peculiar design with sharp knives, holes up to 120 mm deep are created in the soil, which improves moisture absorption and drainage. The soil is saturated with oxygen and promotes the activation of beneficial microorganisms.
