A vegetation clearing implement features at least one blade arranged for conveyance over an area of land in a forward working direction. Each blade features a respective serrated cutting edge positioned at a leading side of the blade. The serrated cutting edge lies along an oblique axis that resides at an oblique angle to the forward working direction. The serrated cutting edge features alternating crests and troughs situated along the oblique axis, and each trough has a concave curvature between a pair of adjacent crests. A slope of the concave curvature at its leading end is more parallel to the forward working direction than its trailing end. This provides a gradual increase in the aggression of cut as the equipment moves through the vegetative material to provide for smooth, efficient travel of the implement during a vegetation clearing operation.
