Replacement wavy (fluted) coulter disc blade for disc harrows, vertical tillage equipment, and no-till seed drills, commercial part number 55900. Designed for vertical soil fracturing, precise seedbed preparation, and efficient crop residue sizing without excessive soil inversion. Its wave geometry delivers localized soil shattering and superior ground penetration even in heavy, hard-packed ground conditions. Manufactured from high-tensile 30 MnB5 heat-treated boron steel, it ensures exceptional resistance to abrasive wear along with structural elasticity to endure sudden stone impacts. Features an enlarged overall diameter of 510 mm, a 4.0 mm plate thickness, and a 31 mm central square bore for mounting on standard gang axles.

Fitting tipsBefore installing the disc onto the square gang axle, thoroughly clean the shaft contact area and adjacent spool spacers to remove rust, soil buildup, and metal burrs. Slide the blade into position, ensuring the 31 mm square bore fits smoothly without binding to avoid localized stress points on the center hole corners. Align the entire disc gang along the axle and torque the gang axle nut to the equipment manufacturer's specified rating. Recheck the tightness of the disc pack assembly after the initial operational hours in the field.
