Description / Abstract:
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.
NOTE—For some heavy duty applications, cross sections with
larger blunts and greater bevel angles may be required.
Purpose—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.
Rationale—This document has been reaffirmed to
comply with the SAE 5-year Review policy.
