You don't mention the brand of lawn mower. If it is a Sears or Craftsman, you have to get it at Sears. If it is another brand, try a Google search to see if there is a downloadable manual online.
You can get an owner's manual for a Sears lawn mower when you purchase the product. Other than that, you may be able to ask in the store and see if they will sell the manual by itself.
The size of belt that fits a Quantom Pro Lawn mower will vary depending on the model of the mower. The belts can usually be bought in any hardware store or at retail stores such as Sears.
