LRRB guide offers tips for selecting the best cutting edge

A snowplow removes snow from a paved road

When it comes to maintenance operations, choosing the best cutting edge for plowing snow or blading gravel roadways is a complex, yet critical, decision. With key factors like road types, traffic volumes, snow and ice patterns, and operator behaviors for agencies to consider, along with price ranges and functionality, there is no one-size-fits-all answer. To help inform and streamline this decision-making process, the Minnesota Local Road Research Board (LRRB) has developed a new resource, Smart Selection of Cutting Edges: A Practical Guide for Minnesota’s Cities and Counties.

Cutting edges are essential tools for performance, safety, and cost control. Because selecting the proper cutting edge will keep trucks on the road longer and allow crews to stay focused on completing their routes, agencies should consider operational efficiencies and reduced downtime as part of the life-cycle value. Choosing the best option also creates additional safeguards for workers, roads, and the environment; the proper edge will maximize mechanical snow and ice removal, minimize reliance on chlorides, protect road surfaces, and keep operators safe.

To improve the selection process, the guide proposes defining the road surface and plowing purpose; matching the edge to the environment and need; considering speed, down pressure, and road surface temperature; reviewing the cost and life cycle; and piloting and evaluating the edge. Overall, agencies should treat cutting edge selection as a strategic investment, rather than a routine purchase, to see better results, longer edge life, and lower total costs.
