EarthForce poly and steel cutting edges in various sizes are used for many applications. Steel cutting edges have superior scraping capabilities while increasing the life of your bucket edge. Polyurethane bucket edges are ideal for apartment complexes, schools, and hospitals, as they are quieter than steel. When used on fresh snow and slushy conditions, polyurethane edges mold to the surface and creates a squeegee effect. Best for applications where plowing surface damage is a concern like driveways, pavestones, and landscaping. Blank cutting edges are designed for you to cut the length of your bucket and drill holes to match the bucket holes. Easy to cut and drill with standard power tools.
