AYP Mower Blade 20" 5/8" Part No: A-B1EP1018 129277 131694 133346 134871 145106 340-157 6235 752233 95-051

What It Is

This is a 20-inch, 5/8-inch center-hole mower blade from AYP, designed for standard residential walk-behind mowers. It’s a straight, low-lift blade suited for general grass cutting, not mulching or bagging.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Your mower deck must accept a 20-inch blade. Measure the existing blade tip-to-tip or check your owner’s manual.
• Center hole: The hole is 5/8-inch diameter. This is common on AYP/Craftsman/Husqvarna/Poulan models, but verify yours matches.
• OEM cross-references: This blade replaces AYP part numbers 129277, 131694, 133346, 134871, 145106, 340-157, 6235, 752233, and 95-051. It fits many Craftsman, Husqvarna, and Poulan Pro mowers from the 2000s onward. If your mower uses a different OEM number, measure before buying.

Not compatible with 7/8-inch center hole blades (common on MTD/Troy-Bilt) or 21-inch decks.

Key Things to Know

• Quality: Made from heat-treated steel. It’s a solid OEM-replacement blade, not a premium or coated blade. Expect average durability.
• Installation: Requires a socket wrench and torque to 35–40 ft-lbs. Use a blade stop or block of wood to hold it. Check the blade bolt condition – if it’s worn, replace it.
• Common gotcha: This is a low-lift blade. It won’t mulch leaves well or lift wet grass. If you need mulching or bagging performance, look for a high-lift or mulching blade.
• Balancing: New blades are balanced from the factory, but always check with a blade balancer after sharpening.

Should You Buy It

Buy this if you need a direct drop-in replacement for a standard 20-inch 5/8-inch hole blade on a Craftsman, Husqvarna, or Poulan walk-behind mower and you primarily cut dry, level grass. Skip it if you want mulching, bagging, or a premium coated blade – this is basic, functional, and budget-friendly.
