Chassis and frame of the seed unit form a fixed unit. It is comparable to the principle of the Pronto 7 to 9 DC without seed hopper. The DiscSystem and the TurboDisc seed are lifted via hydraulic cylinders. The rigid draw of the seeding unit is carried by the seed wagon and follows the seed wagon like a one-axle trailer. Despite the large working width it folds to a transport width of 3 m.
Due to the concept of the seed wagon the filling level of the seed hopper does not influence the working depth of the seed unit. The HORSCH seed wagon concept provides large hopper capacities for working widths starting at 8 m. Even without a filling auger the feed openings of the seed wagon are easily accessible as the wings of the Pronto seed unit do not affect the filling process.
The double hopper system allows for transporting fertiliser along and incorporating it directly into the soil by means of the PPF system (NOT for Pronto 12 SW with 3 m transport width). A double venturi below the metering device allows for a mechanical, or optionally an electronical half-width shut-off. Thus, overlaps can be avoided and seed and fertiliser can be saved. A filling auger is available as an option.
