Product Description
Sold as a set of 3 aftermarket replacement blades for commercial mower applications using blade family 103-1577 / 20843 / 00273000 / 112111-01. Each blade measures 16-1/4″ in length and 2-1/2″ in width, with a 5/8″ round center hole. The source file explicitly states this family as Blades for 32″ & 3 Blades for 48″ Deck, and external search results support that mixed 32″ / 48″ usage pattern. Because this listing is sold as 3 blades, it is best understood as a 48-inch set or a bulk pack within a mixed 32″ / 48″ family.
