The RDP and RPP subsoiler range is designed for medium-power tractors, with a chassis and shank angle that allow easy penetration in hard soils. They feature shear-bolt-protected, reversible tips for safety and durability, and can be equipped with optional rear discs to break up clods. Two hydraulic cylinders control depth and cutting angle. These subsoilers operate efficiently at high speeds by converting ripper force into downward pressure on the tractor, allowing smaller tractors to achieve deeper ripping than conventional models.
