The genuine Western 63990 Cutting Edge Kit serves as the essential wear component for your 9-foot Western Pro Plus and Pro Plus HD straight-blade plows. Manufactured from premium, high-carbon steel, this 1/2-inch thick edge is engineered to withstand the punishing abrasion of concrete, asphalt, and packed ice, ensuring your moldboard remains protected against severe pavement friction. Consequently, replacing a worn, thinned, or uneven edge restores the aggressive scraping geometry required to peel hard-packed snow down to the road surface, maximizing the efficiency of every pass.
This kit is precision-manufactured to match the exact dimensions and hole alignment of your Pro Plus/Pro Plus HD blade. Because it is a genuine factory component, installation is straightforward and precise, allowing maintenance crews to swap out old, damaged edges without the need for custom drilling or field modification. The comprehensive kit includes the high-carbon steel blade and the necessary heavy-duty carriage bolts and hardware to ensure a secure, vibration-resistant mount that will not shear under the intense pressure of commercial clearing.
For fleet owners and professionals, maintaining a sharp cutting edge is one of the most effective ways to reduce operator fatigue and fuel consumption. By utilizing this original manufacturer-grade replacement, you preserve the structural integrity of your plow’s moldboard and ensure your equipment stays ready for the next shift.
