You are bidding on a NOS Genuine MTD/Ariens/Troy-Bilt/Cub Cadet Blade Adapter.
Fits various Mowers, Splined Shaft. See pictures. 
MTD part number 753-0485, 953-0485, and more.

We cleaned out a Jacobsen/Cushman/Briggs/Tecumseh/Smithco dealer that went out of business a few years back and are FINALLY getting around to listing more of it. Check our other items and check back often as we will be adding much more over the next few weeks. If you need a manual you don't see listed, just ask! We more than likely have it around here somewhere!

Ask all questions prior to bidding. Please see picture. Thanks for looking and good luck bidding!
