M113518 M115496 (3) Toothed Mulcher Mower Blades Fits John Deere 54" Deck

I recently purchased a mower that needed these blades. I peeked under the deck and saw some really ugly, twisted, bent and broken blades, so I ordered these to replace them. When i removed the old blades, I found that they had been installed upside down, That made the defector the leading edge and also lead to the twisting of the blades, as the now cutting edge was not in line with the rest of the blade. There was a drastic improvement in performance with the installation of the blades. Very pleased with the performance of the mower with these new blades. Only time will tell if they last.
