3PK 91-623 Lawn Mower Blades 71440001 Fits Wright 52" Stander Mowers

What It Is

These are a set of three aftermarket mulching or standard blades (part cross-reference 91-623, 71440001) designed specifically for Wright 52" Stander commercial zero-turn mowers. They are used for cutting grass on large residential or commercial properties.

Fitment & Compatibility

• Deck size: Fits only 52-inch cutting decks. Measure your deck width to confirm.
• Model check: Confirmed for Wright Stander models with 52" decks (e.g., Stander 52", Stander X 52"). Verify your mower’s model number.
• OEM cross-reference: Replaces Wright OEM part numbers 71440001 and 91-623. Aftermarket, not OEM.
• Blade dimensions: Length typically 18.5", center hole 5/8" hex, 0.25" thick. Measure your existing blade’s length, hole shape, and thickness before ordering. If yours is longer or has a different hole, these won’t fit.
• Quantity: Sold as a set of 3 (one for each spindle). You need all three for a 52" deck.

Key Things to Know

• Quality: Aftermarket blades are often less durable than OEM. Check reviews for balance and sharpness out of the box. At 5.0 stars (3 reviews), the sample is small.
• Installation: Moderate difficulty. You’ll need a socket wrench, torque wrench (recommended 70-90 ft-lbs), and jack stands to lift the deck. Always disconnect the spark plug first.
• Common gotcha: Aftermarket blades may require balancing before installation. Use a blade balancer to avoid vibration and spindle damage.
• Cutting performance: Expect good mulching or bagging with proper sharpening, but aftermarket steel may dull faster than OEM.

Should You Buy It

Buy these if you own a Wright 52" Stander, want to save money over OEM blades, and are comfortable with basic mower maintenance (balancing, torquing). They’re a solid budget option for homeowners or light commercial use, but for heavy-duty commercial mowing or maximum durability, stick with OEM Wright blades.
