For cutting edges used on buckets for loaders defined in SAE J1057a. The dimensions are applicable to rolled, cast, forged, flame cut, and machined cutting edge sections. Straight cutting edges are defined as those whose leading edge and rear edge are parallel and, thus, are of constant cross section. For "straight cutting edge sections with bolt holes," see SAE J1304 FEB85.

To specify dimensions for straight cutting edge cross sections to be used on loader buckets as described by SAE J731d. This recommended practice was conceived to minimize the number of different cutting edge sections used, therefore, allowing for possible future standardization of replacement cutting edges and weld-on tooth adapters.
