I did indeed upgrade to the Fastrak 54. I went with the Fastrak and not an SD as I'm a homeowner. It has the mulch kit installed and mulches my Zoysia at 2.5 inches like a champ.
It isolates each blade with a separate baffle. And I am very happy with the mower and glad my dealer worked with me on the upgrade.
I even put a coat of wax on it to make blowing off clippings easy.
Now if I can just keep my wife off it!!:laughing:
