This genuine Craftsman shaft assembly is an original replacement part sourced directly from the manufacturer and is designed for use with riding lawn mowers. It fits into the mandrel housing and serves as a critical connection between the mower blade and the pulley, allowing for smooth and efficient power transfer. This part is sold individually and is ideal for restoring proper function to your mower’s cutting system. Please note that the top bearing and housing are not included and must be purchased separately if needed.

The only vendor I've found that stocks the shaft independent of the mandrel assembly..
While the part was exactly what I needed, shipping was very slow, nearly two weeks. Shipping costs and the time between ordering and receipt are equally important to me from a total value of service standpoint. The cost of expedited delivery was more than the part itself, thus, wasn't a sensible option.

The part worked out great. Only problem was it took 1 1/2 weeks to get. Grass was pretty tall by the time I got the part.

The star that goes into the blade to keep it from spinning was worn out. I took the top bolt off, took the pulley off and the entire assembly came out through the bottom. Attached blades to the new shaft assembly and inserted through the bottom, put on the pulley and tightened the bolt. Voila now cutting like brand new!
