    Comments about ACE HARDWARE Ace® 3-In-1 Universal 20"" Mower Blade:

    So I have this 1997 Toro mower that I bought off some dude on the CL about six years ago. I only put gas in this thing. Haven't changed the oil, the spark plug...none of that business. It starts right up every spring, like a champ! (I should probably take better care of it.) thick and/or damp grass, it struggles. You can tell the mower's having difficulty cutting. I'm sure there are more powerful engines out there but the blade's gotta be pretty dull.

    So I took the blade into Ace to get it sharpened but they were backed up and said it might be a week. So I bought this universal blade. Super easy to work with. It has an over-sized, almost oval-shaped hole in the center but comes with some custom-fit metal fittings to go in there that will fit your mower's crank shaft or whatever.

    After having taken the original blade off and dropping it off at the Ace, I bought this thing, opened it up, read the clear instructions, and fitted the piece into place, popped the blade on, tightened it up, and off I went. Super easy for someone who normally calls a contractor for everything.

    My grass has been long after heavy rains lately. And it was slightly damp. First mow of the season, I thought for sure this thing was going to choke up and die with the tall, wet grasses. To my amazement, this incredible blade helped it power right through! I wish I could post a picture. The grass was higher than the top of the mower's engine in spots. This blade allowed my mower to power through my Serengeti back yard like a hero. Love it.

    Double check your mower brand and blade size and go buy it! If for some reason it doesn't fit, keep the packaging and bring it back to the Ace Place. I'm super happy w/this!!

    Didn't fit Lawnboy

    This said it was universal and would fit my mower but it didn't. My Lawnboy has a curved area where the blade bolts to the mower but this was flat.
