I have a 54" Hustler SD ztr and the OEM blades dull and get dings in the cutting edge rather quickly for my taste. I have been searching the web and cannot find a cross to the gator blade. Is there a better blade than the "soft" OEM blade out there? the part# of the blade on my mower is 797696. if there are better blades out there would my dealer carry them? Thanks for your help.
