Yes I have…
A few problems, the first set for my 72” ZTR were cut wrong and didn’t mow right /forums/images/graemlins/crazy.gif. They did ship another set, but it did not cut evenly. Too much air moving around 12 blades with lift on each one was much too much air and it pushed the grass down instead of lifting it. Nice idea, just dose not work.
I replaced every other blade with a flat knife made for a disk mower, it helped A LOT… but still not as nice a cut as factory blades.
The 4 large circles cut in the round plate do mulch about anything that you mow, that part of the blade is ok, but the over all performance was not to my expectations.
The guy that makes the blades is a nice guy but his blades don’t work on a large deck, they may work fine on a single blade set up. This was 2 years ago they may have corrected the problem? I think you will wish you had just bought $200+ worth of factory blades and used that lifetime supply /forums/images/graemlins/smirk.gif… keep mowin’… KennyV.
