42 Inch Mower Blades for Craftsman 532138971, Compatible with Hus-qvarna/Poulan 42'' Deck Mower Blades Replace for 532138971, 127843, 134149,532138498, 531307224, 2 Pack

What It Is

This is a 2-pack of 42-inch replacement mower blades designed for Craftsman, Husqvarna, and Poulan riding mowers with a 42-inch cutting deck. They are a direct replacement for OEM part numbers 532138971 and several compatible cross-references, intended for medium-duty residential mowing.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck (measure deck width from side to side). These blades are specifically for Craftsman models using OEM part 532138971, plus Husqvarna/Poulan models using 127843, 134149, 532138498, or 531307224. Check your owner’s manual or existing blade for these numbers. Critical measurements: blade length = 21 inches (each of the 2 blades), center hole diameter = 5/8 inch, and thickness = 0.1875 inch (3/16"). They will not fit 46-inch or 54-inch decks.

Key Things to Know

• Quality: Aftermarket blades; many users report they are slightly thinner or lighter than OEM, but still durable for typical lawn use.
• Installation: Easy DIY swap—requires a wrench and socket (typically 5/8" or 3/4" for the bolt). Always disconnect the spark plug and lift the mower safely.
• Common gotcha: The blade’s “air lift” design may differ slightly from OEM, which can affect grass discharge or mulching. If you have a bagger, test first.
• Sharpening: These are disposable; resharpen once or twice, but replace when nicked or bent.

Should You Buy It

If you have a 42-inch Craftsman, Husqvarna, or Poulan riding mower and want a budget-friendly, direct-fit replacement for OEM blades, this 2-pack is a solid value for residential use. It’s not for heavy commercial mowing or decks requiring exact OEM specs, but for most homeowners, it works well.
