Parts and Product Categories
We source and quote moldboard cutting edges, curved or flat grader blades, end bits, scarifier teeth, cutting-edge bolts, nuts and related wear hardware. Products shown online represent available catalog categories, but stock status, lead time and compatibility can change by part number and application.
Shop grader blades and cutting edges or browse all cutting edges and blades.
Model, Serial Number and Fitment Guidance
Before ordering, provide the complete GD model and dash series, serial number, moldboard width, blade length, thickness and curvature, hole diameter, hole count and center-to-center spacing. A model decal alone is not enough when a manufacturer revised a machine within the same family. For undercarriage, measure both sides and inspect mating components; for ground-engaging tools, confirm the complete edge, adapter or holder system.
Availability, Shipping and Quote Support
Some products can be purchased online, while oversized, heavy or application-specific parts may require a freight or special-order quote. Shipping method, cost and lead time depend on product weight, dimensions, destination and supplier availability. We will confirm compatible options and current availability before finalizing a quote. Review our shipping and returns information, submit a Part Finder Request for identification help, or request pricing and availability. Photos and measurements often prevent delays.
Komatsu Motor Grader Parts FAQs
Can I order a Komatsu grader blade by length alone?
No. Length, thickness, width, curvature, hole diameter and hole spacing must match. Serrated, heat-treated and carbide options also serve different applications.
Which edge material is best for my grader?
The answer depends on abrasion, impact, road material, snow work and desired service life. Describe the application and current wear pattern when requesting a quote.
