I studied this mower from one end to the other. Local HD has one. It most definitely is NOT a 7 gauge deck, though every Home Depot ad, GXI's web site, Northern Tool (the Stanley Zs), all of them claim it is 7 gauge. 7 gauge is 3/16" thick, the industry standard for a commercial mower deck. I could be mistaken- the Beast may have a 12 gauge deck. But I know my metal, and I know what 7ga looks like.
