8Ten LawnRAZOR Lawn Mower Deck Blade

These blades are designed as a direct replacement for Gravely part number 00450300. Before purchasing, verify that your mower deck is 52 inches and that your current blade specifications match the 17.6875-inch length and 2.5-inch width of this set.

High-lift blades feature a more aggressive wing design that creates increased airflow under the mower deck. This suction helps stand the grass upright before it is cut and propels the clippings out of the discharge chute more effectively, resulting in a cleaner, more uniform finish.

Yes, this package includes three blades, which is the standard requirement for a 52-inch Gravely mower deck. Replacing all three at once is recommended to maintain balanced cutting performance and prevent vibration issues.

These are high-lift blades, which are primarily engineered for side discharge and bagging applications where airflow is critical for moving clippings. While they can cut grass effectively, they may not provide the same fine-chopping performance as dedicated mulching blades.

You should replace your blades if you notice the tips of your grass looking frayed or brown after mowing, which indicates a dull edge. Additionally, check for significant metal loss, deep gouges, or bending, all of which compromise the balance of the blade and the quality of your cut.
