RAParts High Lift Mower Deck Blades

These blades are designed as a direct replacement for part number 21546095 and are compatible with Ariens 42-inch mower decks. We recommend verifying your original part number against this specification before purchasing to ensure a proper fit.

High lift blades feature a more aggressive wing design that creates stronger airflow under the mower deck. This increased suction pulls grass blades upright for a cleaner cut and helps propel clippings out of the discharge chute, which prevents clumping and buildup.

Yes, this set includes two blades, and it is best practice to replace both simultaneously. Installing a new blade alongside an old, worn one can cause an imbalance in the mower deck, leading to uneven cutting and potential vibration issues.

These are designed as a direct replacement, meaning they should install just like your original equipment without requiring any modifications. If you are comfortable using basic hand tools to remove and secure the blade bolts, you should find the process straightforward.

These are high-lift blades specifically engineered for efficient grass discharge. While they will cut the grass effectively, they are not optimized for mulching, which typically requires a different blade profile designed to keep clippings suspended under the deck for finer cutting.
