The Meg Mo blades are a good idea on paper, and apparently will work on some systems. I got a set for my 6 foot ZTR did not work, the center set pushed grass down and gave a bad , bad cut:thumbdown:. Mr Megli is a good guy, tried to be helpful but still not working out. I now have (2) sets of 72 inch Meg MO that will not mow. They would do ok for rough cut work, but not a finish cut.
I suspect it has a problem with some side discharge decks, or maby larger decks. My machine is a commercial grade, over $30k diesel/cab ZTR mower, it flies with regular blades and will cut perfect with gator blades... but is no good with either set of Meg Mo. KennyV
By the way you can experiment with disc blades of various shapes on your 'meg mo circles'... just shop around for the correct length ... they hold an edge well.
