Cutting edge assemblies are normally utilized on the leading edge of implements to protect the leading edge of the implement from wear. In order to have a readily removable cutting edge assembly that can be replaced in the field, it is necessary to provide fastening means to retain the respective components to the implement. Since a surface and corresponding holes in the respective elements of the cutting edge assembly must be provided, the respective components are weakened and thus tend to break when used under high load conditions. In this subject arrangement, a cutting edge assembly is provided having a base edge with a scalloped leading edge. A plurality of teeth is provided and each tooth is releasably attached in space relation to the base edge. A plurality of base edge protectors is also provided and each protector is connected to the base edge between the respective teeth of the plurality of teeth. Furthermore, each tooth of the plurality of teeth has a bottom portion which extends rearwardly from a forward end portion and subtends from a top portion thereof between two holes located therein. The plurality of teeth and the plurality of base edge protectors provide a substantially continuous cutting edge for the implement while the bottom portion provides additional strength to the respective teeth.
A Cutting edge assembly adapted for connection to an implement, the cutting edge assembly comprising:
A tooth adapted for releasable connect to a base edge of an implement wherein a leading edge of the base edge is scalloped, the tooth comprising:
