Will this blade fit my 22" mower deck?

The Fismiuta 331740B is designed for 22" mower decks with a 5-point star center mount. It replaces several widely used OEM numbers, but you should verify your mower’s specifications before ordering to ensure compatibility.

• Blade dimensions: 22" length × 2-1/2" width × 0.118" thickness.
• Center: 5-point star hole to match common Craftsman and Husqvarna mounts.

How does this blade improve cutting and lawn health?

Fismiuta blades arrive pre-sharpened at a factory angle optimized for clean slicing, reducing grass tearing and promoting faster recovery. A sharper, balanced blade creates finer clippings that decompose quicker, helping maintain a neater, healthier turf.

• Pre-sharpened edges for immediate use and cleaner cuts.
• Balanced manufacturing to reduce vibration and improve cut quality.
• Best for well-manicured lawns and shorter grass; suitable for sandy soils.

What materials and treatments make this blade durable?

This replacement uses premium high-carbon steel tempered for hardness and fatigue resistance, so it withstands repeated impacts and edge wear. Finsiuta applies rust-inhibiting treatments, paint and a baked finish to slow corrosion and extend useful life even when stored in damp conditions.

• High-carbon steel construction with tempering for strength.
• Rust inhibitors plus painted, baked surface finish for weather resistance.
• Precision-edge grinding for consistent sharpness across the blade length.

How easy is installation and maintenance?

Installing the Fismiuta 331740B is straightforward for anyone comfortable changing mower blades; it follows the same mounting pattern as the OEM parts it replaces. Routine inspections and occasional re-sharpening will keep performance high and extend service intervals.

• Fits the same 5-point star mounting pattern as many OEM blades—no modification expected.
• Pre-sharpened, so it’s ready to mow right away after proper installation and torqueing.
• Simple maintenance: clean debris, check balance, and re-sharpen as needed.

Who is this for: The Fismiuta 331740B suits homeowners and landscapers who run 22" riding or walk-behind decks that accept a 5-point star hub and need a reliable, OEM-replacement-quality blade. It’s ideal for those who want a pre-sharpened, corrosion-resistant blade that provides a cleaner cut for well-kept lawns and tolerates sandy conditions. Always confirm your mower’s part number and center hole pattern before buying to ensure proper fit.
