Husqvarna Lawn Mower Deck Blade

This blade is designed for standard 21-inch mower decks and corresponds to OEM part number 5391017-33. Before purchasing, verify your current blade's length and center hole pattern against your mower's manual or the existing blade to ensure a compatible fit.

The notched tip design is engineered to improve cutting efficiency by creating better airflow under the mower deck. This helps lift grass blades upright for a cleaner, more precise cut compared to standard flat-edged blades.

Yes, this is a high-lift blade, which is versatile enough to handle both bagging and discharging. The high-lift design generates strong suction, which is particularly effective at moving clippings into a bag or dispersing them evenly.

You should generally replace your blade once it shows signs of significant wear, such as dull edges, nicks, or bending. If you notice your grass is tearing rather than cutting cleanly, it is likely time to swap it for a new one to maintain lawn health.

Yes, because this blade is constructed from durable steel, it can be sharpened. However, ensure you maintain the original angle of the cutting edge to preserve the blade's performance and balance.
