• The open frame design with large clearances guarantees blockage-free operation even in high amounts of organic mass.
• The 620 mm diameter concave discs overlap between rows to ensure that all soil is moved even at shallow working depths.
• Legs are mounted on strong hinges, with overload protection via robust spiral springs, to ensure the discs stay on track even in difficult conditions.
• Each row of the notched discs has height and angle adjustable rebound harrows, controlling the soil flow from the discs and, when working diagonally across the rows, helping to complete a thorough straw distribution.
• In working widths of 4 to 6 metres, the semi-mounted Rubin 9 can be fitted with a light, transport axle, or with a combination axle for use together with the Solitair pneumatic seed drill.
