Motor Grader Cutting Edge – Hole Pattern, Size and Wear Guide
A motor grader cutting edge is a wear part fixed to the moldboard. The original title contained a spelling error; this page now uses the correct term and focuses on measurable fitment evidence.
Ordering basis: Measure the edge and hole pattern, and confirm whether the blade uses straight, curved or segmented edges.
Cutting-edge measurements
Record length, width and thickness.
Measure hole diameter, spacing and edge distance.
Count holes and note countersink or square-neck geometry.
Confirm straight, curved, centre or end-bit position.
Use wear to inspect the moldboard
Uneven wear may indicate incorrect blade angle, loose bolts, a bent moldboard or operation on one side. Inspect the mounting face and bolt holes before fitting a new edge.
Safe replacement practice
Support the blade securely, clean the mounting face and replace damaged fasteners. Tighten in the specified sequence and recheck after initial operation.

FAQ
Can a cutting edge be matched by length only?
No. Width, thickness, hole pattern, bolt geometry and blade position must match.
What causes bolt holes to elongate?
Loose fasteners, worn mounting faces or repeated impact can move the edge.
Should end bits be checked at the same time?
Yes. Their wear and interface can affect full blade protection.
Compatibility note: Use physical dimensions and the moldboard arrangement for final selection.
