I have an XT3 GSX with a 54" fabricated deck. The unit is currently in my storage barn for the winter and the doors are snowed shut. I'd like to order some Gator blades to put on in the spring (if that ever happens), but I don't know what number to order. I previously had them on an older Cub with a 46" deck but don't remember where I ordered them from. Any help with what number I need and where to get them would be greatly appreciated. Thanks.
