Everybody I know that uses them swears by them. I have not been able to get a set for my Kubota but hopefully soon they will have them available because not only are they better but usually cheaper than OEM blades as well.
So my question to the reponders in this thread so far is.....if you use these "Gator blades", does the mower need a "mulching kit"???? For some, like my old Craftsman YS4500 Lawn Tractor, that consisted of simply a plastic cover that went over the discharge opening and mulching blades. It worked "pretty well" unless the grass got to tall!! The "mulching kit" recommended for my Gravely Pro-Turn 152 actually includes "circular" metal sheets that mount underneath the deck to create "circular enclosures" around each of the 3 blades(as well as mulching blades and maybe even a discharge opening cover..not sure about that). What I read in this thread seems to "imply" just putting on the Gator blades turns a ZTR mower into a "mulcher". But, when I asked several dealers that sold different brands of ZTR's about a mulch kit for my ZTR if I purchased their mower(because of my experience using the one on the lawn tractor) they all told me "wait until you have mowed with this machine because with it's blade tip speed it is COMPLETELY different from that old LT". And thus far, with the factory "hi-lift" blades, I have yet to witness the first grass clipping left after mowing......soooooo, what do I really need a "mulching blade/kit" for?????
