A cultivating disc for a tillage implement includes an attachment portion positioned at a radial center of the cultivating disc. The attachment portion includes one or more attachment features configured to couple the cultivating disc to the tillage implement about an axis of rotation of the cultivating disc. The attachment portion extends along a first plane perpendicular to the axis of rotation of the cultivating disc. The cultivating disc also includes a cutting edge portion positioned at a distal end of the cultivating disc relative to the axis of rotation. The cutting edge portion extends along a second plane parallel to the first plane. The cultivating disc further includes a curved connecting portion positioned between and connecting the attachment portion to the cutting edge portion. The curved connecting portion further defines one or more radii of curvature.
