I have a Bolens riding lawn mower and the belt snapped. We have a replacement belt, but can't find my owners manual - I need to know where/how to tighten it? Anybody please? I have accessed the company's website to get a manual download, however they do for whatever reason do not recognize the serial and model number on the riding mower... I am not sure why - as I have tried it with dots, slashes, hyphens and spaces [the only thing missing are the bells and whistles] and still no results... I am sure eventually I'll figure it out - or take to the next repair place - it's simply that I would have liked to get the grass cut this weekend...
