The Pegasus tractor mounted disc cultivator is universally usable for stubble tilth, for basic soil cultivation and the seed bed preparation. The shallow mixing of plant residues, e.g. stubble, straw and catch crop with the surface soil provides best protection against soil erosion and capping. When completely working the soil across the field with wide wing shares favorable pre-conditions are provided for a quick germination of volunteer grain and weed seeds. Compatible AMAZONE cage-, tooth packer- or wedge ring rollers for a targeted recompaction optimize the germination conditions for volunteer grain and weed seeds. The Pegasus tractor mounted disc cultivator is available in working widths of 3 up to 5 m. The hydraulically foldable versions of 4 m and 5 m allow a trouble free road transport at a transport width of 3 m.
