Product Description
Sold as a set of 6 aftermarket replacement blades for John Deere mower applications using blade family TCU15881 / M128485 / M131958 / M144196 / M163983. Each blade measures 20-7/8″ in length and 2.50″ in width. The source file specifies a 7/8″ center hole, and external search results support that same 7/8″ center-hole specification for this family. This blade family is widely used on 60″ decks. Many applications in this family use 3 blades per deck, so this 6-piece listing should be understood as a bulk pack covering two blade sets.

Installation Tips

Always disconnect the spark plug wire before removing or installing blades. Replace bent, cracked, or badly worn blades immediately.
