420463 Blade Compatible with Crafts man Hus qvarna Pou LAN 22 inch Mowers, Replaces 331740B, 421825, 437601, 532437601, Black, 1pc

What It Is

This is a 22-inch replacement lawn mower blade designed for gas-powered walk-behind mowers from Craftsman, Husqvarna, and Poulan Pro. It cuts grass by spinning at high speed and is intended for standard residential mowing on flat to moderately uneven turf.

Fitment & Compatibility

Before buying, confirm your mower deck size is exactly 22 inches—measure from blade tip to blade tip if unsure. This blade directly replaces OEM part numbers 331740B, 421825, 437601, and 532437601. It fits most Craftsman, Husqvarna, and Poulan Pro models with a 22-inch stamped steel deck, but double-check your mower’s model number against the compatibility list provided by the seller. The blade has a 5-point star center hole and a 1-inch diameter arbor hole. If your mower uses a different center hole shape (e.g., diamond or oval), this blade will not fit. Aftermarket blades may have slightly different balance or sharpness than OEM—verify blade thickness and width match your original.

Key Things to Know

• Quality: Made from heat-treated steel with a black powder coating for rust resistance. 4.8 stars from 14 reviews suggests good sharpness and durability for the price.
• Installation difficulty: Easy if you have a socket set and blade removal tool. Always disconnect the spark plug wire before working under the deck. Torque the blade bolt to 30–45 ft-lb.
• Common gotcha: This is a single blade (1pc), not a set. If your mower uses two blades (most 22-inch Craftsman/Husqvarna models use one), you need only one. Check your current blade count before ordering.
• Balance: Aftermarket blades may need balancing after installation. A cheap blade balancer (or a nail in the wall) can confirm it spins evenly.

Should You Buy It

Buy this if you own a 22-inch Craftsman, Husqvarna, or Poulan Pro mower and want a budget-friendly replacement that matches OEM specs. It’s a solid choice for routine maintenance, but if you need a high-lift blade for bagging thick grass or a mulching blade, look for a specialized design. For standard side-discharge or bagging, this is a reliable, well-rated pick.
