I got that Snowy but I've had a search through all of the parts lists and EMER's and the LOWEST blade listed, and to my limited knowledge, is -.030". If you have a -.060" it means that there's a -.045" blade out there too!. I think that if you look at the size of your blade through a magnifier, you'll find that it's a .060" and the + looks like a -. Just my hunch............ Not all plus sizes were marked + either.
