Unia - 1680130041 - Cutting Disc 460

This disc is the cutting component for a cultivator, mounted on the leading edge of the tine or share to slice through crop residue and surface crust before the working tool engages the soil. It rotates on its hub as the machine advances, reducing draft force and preventing trash buildup on the shank. A worn or blunted disc fails to cut cleanly, causing residue to wrap around the tine and increasing the risk of soil blockage. The manufacturer machines this disc to match the original hub pattern and thickness, ensuring it seats flush against the spacer without requiring additional shims. On installation, verify that the disc rotates freely on the hub and tighten the retaining nut to the specified torque.
