How do I adjust the belt on a honda ride-on mower. It appears to be a cable that creates the tension for the belt driving the blades but I can't find a way to tighten it a little as the belt is a little loose. The belt is new.

Hi,
Most manuals are available directly from Honda at:
Honda Power Equipment - Operator's and Owner's Manuals (http://www.hondapowerequipment.com/products/manuals/Default.aspx)
Peace,
