Product Description
Sold as a set of 4 aftermarket replacement blades for AYP / Craftsman / Husqvarna / Poulan-family mower applications using the 127843 / 138498 / 532138971 blade family. Each blade measures 21″ (533 mm) in length, 2-1/4″ in width, and 0.1500″ in thickness. The center mounting hole is a 5-point star pattern, and the source file specifies right-hand cut direction. This blade family is widely used on 42″ decks. Many 42″ applications in this family use 2 blades per deck, so this 4-piece set is best understood as a bulk pack and buyers should verify both fitment and required order quantity before purchase.

Installation Tips
Confirm your mower’s required blade quantity before ordering, since this listing is sold as a 4-piece pack. Confirm the center hole matches your spindle pattern before installation. Install only where the specified right-hand cut direction matches the original blade design. Always disconnect the spark plug wire before removing or installing blades.
