8TEN LawnRAZOR Blade

The high-lift design features a more aggressive wing angle on the blade, which creates stronger suction. This pulls the grass blades upright before they are cut and helps propel the clippings out of the deck more efficiently, resulting in a cleaner, more uniform finish.

While these blades are designed for Ariens ride-on zero-turn mowers, compatibility depends on your specific deck size and model year. You should verify that your mower requires a 20.5-inch blade with a 0.625-inch center hole before purchasing.

Generally, you should replace your blades once a year or whenever you notice the grass tips are fraying or turning brown after a cut. If you frequently mow over sandy soil or debris, you may need to replace them more often to maintain a sharp edge.

Yes, these steel blades can be sharpened using a bench grinder or a file. However, ensure you remove an equal amount of material from both sides of the blade to keep it balanced, as an unbalanced blade can cause excessive vibration and damage your mower's spindle bearings.

This set is designed for mowers with a three-blade cutting deck, which is standard for many larger Ariens zero-turn models. Replacing all three blades at once ensures even cutting performance and prevents vibration issues that can occur if you mix new blades with worn ones.
