Sorry about your bad switch. Im thinking you have 3 belts and to be honest I wouldn't have my belts that tight even if that's what it called for. . I think the most that could happen is it could slip and you would no it. Just my opinion.
I was thinking you needed to store your yard stuff inside for the winter but I just now noticed you live in Florida. Id be interested in seeing more pictures of your storage shed build as it comes along.
