Gator Blade for MX5060

The Hi-Lift blade number is 115-5059-03 which is available all day long, (to fit a 50" deck Toro MX5060) but I'm told that Gator Blade equivalents aren't available. And, maybe that's true...



I wonder if that so though, or if my supplier doesn't carry them and wants to sell what he has in stock.



What say you?



P.S. My google-fu isn't strong so I didn't find the answer though I've tried...



Thanks!
