3PK Lawn Mower Blades Set Fits Wright 52" Stander Sentar Blade 91-622 71440001

What It Is

This is a set of three 52-inch lawn mower blades designed specifically for Wright Stander and Sentar zero-turn mowers. They replace OEM part numbers 91-622 and 71440001, intended for mulching, bagging, or side-discharge cutting on commercial or residential turf.

Fitment & Compatibility

Before buying, confirm your mower has a 52-inch cutting deck and is a Wright Stander (any model) or Wright Sentar. Measure your existing blades: they must be 17.5 inches long, 2.5 inches wide, with a 1-inch center hole and a 0.5-inch offset for the spindle. If your blades use a different hole pattern or offset, these won’t fit. Aftermarket replacements are not OEM, so double-check the blade thickness (typically 0.203 inches) matches your spindle’s clearance. Avoid these if your mower is a different brand (e.g., John Deere, Husqvarna) or has a non-52-inch deck.

Key Things to Know

• Quality: Made from heat-treated alloy steel, these blades are durable for typical residential and light commercial use, but may wear faster than OEM under heavy daily mowing.
• Installation: Medium difficulty—requires a socket wrench and blade removal tool. Always disconnect the spark plug and use jack stands if lifting the mower.
• Common gotchas: The set includes three blades; ensure all are identical. Some users report needing to rebalance them with a blade balancer before installation to avoid vibration.
• Sharpness: Pre-sharpened but not razor-sharp; they’ll cut well for the first few acres but benefit from a touch-up after heavy use.

Should You Buy It

If you own a Wright 52-inch Stander or Sentar and want an affordable, drop-in replacement for OEM blades, this set is a solid choice for occasional to moderate mowing. For heavy commercial use or if you need exact OEM performance, consider spending more on genuine Wright blades.
