Notched Concave Discs

Ths is an image of a Notched Concave Disc

Notched concave discs provide a very aggressive cutting edge that is well suited for soil penetration (especially when the concavity of the disc is shallow). These discs are also a good choice for residue management.

Measurements

This image depicts the Diameter, Thickness, Concavity, and Edge Type measurements of the blades This image depicts the Notch Width and Notch Depth measurements of the blade
