Robust Construction for Backhoe Loading Applications
The CASE 580 Backhoe Loader Cutting Edge 112946A1 features a double beveled reversible design. It is built specifically for the CASE 580 series backhoe loaders. The blade measures 0.75 inch thick, 6 inches wide, and 83.125 inches long. Consequently, it provides full-width protection for the loader bucket. The heat-treated steel construction ensures consistent hardness throughout the blade. Therefore, it resists wear from abrasive materials like gravel, sand, and demolition debris. Additionally, the reversible feature allows operators to flip the edge when one bevel becomes dull. As a result, service life effectively doubles compared to single-bevel alternatives.
Simple Installation with Complete Hardware Package
This cutting edge includes all necessary mounting hardware for quick installation. The blade has 10 bolt holes with precise spacing of 8.5 inches from center to center. Additionally, the first hole sits 3.344 inches from the bucket edge. These measurements match CASE OEM specifications exactly. Therefore, no drilling or modification is required. The kit includes 10 pieces of 3/4″ x 2-1/4″ plow bolts and 10 pieces of 3/4″ hex nuts. For best results, clean the bucket mounting surface thoroughly before installation. Then, apply anti-seize compound to prevent thread corrosion. Finally, torque all bolts evenly in a crossing pattern. When the first bevel wears out, simply flip the blade and reuse the existing hardware. Consequently, maintenance downtime stays minimal.
