Large Diagram on how to put on the belts on this type of riding lawnmower

Try a company like this Murray 42576x92B Parts List and Diagram - (2000) : eReplacementParts.com (http://www.ereplacementparts.com/murray-42576x92b-2000-4234-lawn-tractor-parts-c-17887_17888_27656.html) to get a manual.

Hi,
That is one of the good places to go, but it is HTML format, so I try a couple of others before I settle for doing separate downloads. My first choice is Outdoor Distributors for a pdf version that is all-in-one and optimized for size. It is in fact just over 175Kb, a manageable size for most anyone. Includes the electrical schematic (a plus) but Murray never gives the engine numbers (boo.) It is at:

And is attached.
Peace,
Clarke
