I know many of you seeing these pic's will not believe me but I swear this is the truth. What you see is a new fusion blade and one that has been on my 52" MULCHING Super Z since June! Today is Dec 5th. I mow over 60 St Augustine lawns per week. The old blade has ONLY been sharpened 4 times yet it still cuts clean without tearing the grass blades. Normally, I would have had to buy about 5 -6 sets of normal blades to get me through the season. Thanks to the Fusion blades I've saved a ton of money and time changing and sharpening. Keep up the good work Hustler and thanks!
