Outstanding Quality Replacement!, heck, I'd even say this Rotary brand is better/thicker than the original, actually it should be the original!I'm verrrrrrry happy to have found this exact replacement of mower blades for my Simplicity Riding Mower. Already installed them and work Excellent! Nice Quality [email protected] it's half the price of my local Simplicity Dealer, so to have an extra set I bought 6 blades, for the same price of what it would of cost me to get just 3 at my local dealer! (no fault against them though that's the price)Also labeled right on the blades - MADE IN THE USA! by Rotary, and Heavy Duty Excellent Quality Too!2018 EDIT:Looking at my review here 5 years later, Wow, I see the price now buying this "Single" blade has more than doubled!No way pay for that, and so looking again I see you can buy them in a 6 pack at half the price!Here's the link at Amazon:(6) 10094 Rotary Blades Replaces Simplicity 1708229, 1726453A, 1726453
