Product Description
Sold as a set of 2 aftermarket replacement blades for John Deere mower applications using blade family AM100945 / AM100946 / AM100991 / AM104652. Each blade measures 19-1/2″ in length and 3″ in width. The source file states a 3/4″ center hole, while external search results for this family show mixed center-hole measurements across listings. Because of that inconsistency, the safest public-facing description is to keep the center-hole style broad as round center hole and require buyer verification before purchase. This family is commonly sold for 38″ deck applications and as a 2-blade set.

Installation Tips
A 38″ deck in this family typically uses 2 blades. Confirm the center-hole diameter and overall blade size before installation. Always disconnect the spark plug wire before removing or installing blades. Replace bent, cracked, or badly worn blades immediately.
