DISC BLADES

Disc harrow blades and plough discs for disc harrows, offset disc ploughs and soil-working machines, made from spring steel of manganese-steel and boron-steel grades. Different heat-treatment processes are applied according to the material to reach the target hardness — 38–48 HRC, with the target set per grade and part type; the material is selected to your requirement. Diameters from 12″ to 40″ (300–1010 mm), thicknesses from 3 to 12 mm, supplied in notched, concaved, flat and waved profiles; new profiles are produced to your drawing or sample. Monthly output 5,000–8,000 pieces; OEM-compatible sizes with custom diameters, holes and thicknesses on request.

Model numbering system — every blade carries an in-house code: DB-[Type]-[Diameter mm]-[Thickness ×10], where Type = C (Concaved) / N (Notched) / F (Flat & Waved). Example: a 460 mm × 3.5 mm concaved blade = DB-C-460-35; a 660 mm × 6 mm notched blade = DB-N-660-60.

2.Specification — Weight per Blade
