This Genuine OEM blade adapter is a manufacturer-sourced replacement part designed for use with select Craftsman lawn mowers. Made from durable metal and sold individually, this component serves as a direct replacement for a missing or faulty adapter, allowing the user to securely attach the mower blade to the engine shaft. A properly functioning blade adapter is essential for safe and efficient cutting performance.
To ensure correct fit and application, please refer to your model’s parts diagram or owner’s manual before ordering. Replacing a worn or damaged adapter helps maintain blade stability and overall mower reliability.

blade adapter
Ordered the part on 23 March, shipped the same day. However, it took Fed Ex until 7 April to get it. Contacted Fed Ex cs website delay was due to damaged shipping label. Made it to Grove City Oh then shipped to Clinton Pa. Reason for delay...weather. (Grove City is in Ohio south of Newton Falls.) As far as I know, there was no catachismic weather disaster, the airports were not closed and I 71, I 77 and I 75 were intact. Just an FYI.

Mower blade adapter
The part was exactly like original, and seems to be holding up well. I had purchased 2 online at similar prices from other suppliers that failed on first use.

Blade no longer fit on Adapter because it had loosened up.
