Abstract
Disclosed herein are various implementations relating to agricultural tillage discs with a geometry that provides significant advantages over existing models. This improved geometry allows for high-speed tillage while maintaining surface edges more uniformly than would be anticipated in prior models. Additionally, a new edge design allows for an improved edge-durability while maintaining soil penetration.
