Goble Disc Harrows- are used for stubble ploughing and chopping plant residues before cultivation. These implements are very effective on heavy soils in comparison to other disc harrows. It is easy to transport these machines from one field to another by the help of hydraulic lifted wheels placed on equipment. The usage life of harrow chassis and discs are rather long. Discs are made of Boron steel and have 45-50 HRC hardness. Disc diameters 460-510-560-610 mm are adjustable to get the maximum power from the tractor.
