This disc is the cutting component for a tillage implement, mounted on the leading edge of the machine to slice through crop residue and surface crust before the following tines or coulters engage the soil. It rotates on its hub as the machine moves forward, maintaining a consistent cutting depth. A dull or bent disc fails to cut cleanly, leaving unshredded residue that can cause plugging and uneven soil penetration. The original manufacturer’s disc is formed to the correct dish profile and edge angle, which the hub and bearing assembly are designed to match without additional shimming. When replacing, inspect the hub bearings and check the disc for runout after torquing the mounting hardware.
