Bolt-On Grader Blades for Motor Graders

Bolt-On Cutting Edges for Motor Graders

Bolt-on grader blades are among the most important wear components on a motor grader moldboard. They form the working edge and can be replaced when worn without modifying the main blade structure.

The category Grader Blades provides an overview of grader cutting edges, blade designs and typical applications in road construction and maintenance.

Grader Blades and Bolt-On Cutting Edges

Different moldboard systems require different blade profiles, dimensions and bolt patterns. This category focuses on bolt-on grader blades and cutting edges designed for replacement on motor grader moldboards.

Reference number, length, width, thickness, hole count, hole spacing and hole diameter are key factors when selecting the correct blade.

Selection by Reference Number

Many grader cutting edges are identified using the existing reference number. This category includes products suitable for references such as 3G7966, 5D9553, 5D9556, 5D9556HD and 5D9558.

Before ordering, the existing blade should always be compared with the installed component, as different moldboard configurations may require different cutting edge designs.

Typical Applications

Bolt-on grader blades are commonly used in road construction, gravel road maintenance, shoulder work, surface profiling and general grading operations. The bolted design allows individual wear components to be replaced without replacing the complete blade system.

For weld-on applications, suitable products can be found in Wear Bars & Cutting Edges and Wear Bars & Cutting Edges Cut to Size.

Matching Fasteners

Fasteners for bolt-on cutting edges are available in the category Bolts & Nuts.

Check Before Replacement

Before replacing a grader blade, the reference number, length, width, thickness, bolt pattern and installation position should be checked. Accurate measurements help ensure proper fitment and reduce installation work.
