185506A1 Reversible Bolt-On Cutting Edge for CASE 93-Inch Backhoe Loader Buckets

Full Description

The 185506A1 is a straight, reversible, double-bevel cutting edge designed as an aftermarket replacement for selected CASE backhoe-loader front buckets. It is installed across the lower leading edge of the loader bucket and secured through ten pre-drilled mounting positions. Its purpose is to provide a replaceable ground-contact edge while helping protect the bucket’s structural base edge from direct wear during loading, grading, backfilling and general material-handling work.

CASE identifies 185506A1 as a bolt-on cutting edge for a nominal 93-inch bucket. The 93-inch designation refers to the bucket configuration rather than the cutting edge’s exact overall length. The current CASE catalog reference gives an overall length of 94.3 inches (2395.22 mm), while several replacement-parts catalogs list approximately 94.17 inches or 2392 mm. Buyers should compare the supplied drawing and actual edge with the existing bucket before installation.

The consistently published cross-section is 6 inches (152.4 mm) wide and 0.75 inch (19.05 mm) thick. The edge has ten mounting holes and a double-bevel, reversible profile. Reversible construction allows the opposite cutting side to be used after the first side reaches its service limit, provided that the blade, mounting surface and holes remain suitable for reuse.

Model-specific parts diagrams associate 185506A1 with selected CASE 570LXT, 570MXT, 580L, 580M, 580SN and 590SM machines equipped with the corresponding 93-inch or long-lip loader bucket. Other catalog references associate it with certain 580SL, 580SM, 580N, 590SL and 590SN configurations. These references should not be treated as universal fitment because the same backhoe-loader model may use different bucket widths, base edges and hole patterns.

The number 87375240 appears in parts diagrams as an earlier or unpainted cutting-edge reference replaced by 185506A1. By contrast, 134844A1 should not be treated as a direct equivalent because parts catalogs describe it as a different mounting-edge component.

This replacement cutting edge is intended for distributors, importers, repair companies, contractors and fleet operators purchasing CASE-reference bucket wear parts. It is not represented as an original CASE product.

Reference Part Numbers

• 185506A1 — primary CASE reference

• 87375240 — earlier or unpainted cutting-edge reference shown as replaced by 185506A1

134844A1 is not published as an equivalent because available catalogs identify it as a different mounting-edge component.

Applications

• Front loader buckets on compatible backhoe loaders

• Loading loose soil, gravel and aggregate

• Backfilling and general construction work

• Light grading and bucket-edge leveling

• Bucket repair and cutting-edge replacement

• Fleet maintenance and replacement-parts distribution
