Looking for a diagram of 1996 42" cut murray Deck belt diagram.

Hi,
As many times as I have posted this that you did not use the "Search" function!
All I can say try:
Murray decks by crigby (http://opebycrigby.tripod.com/decks/murdeck.html)
One of my sites.
Add by the way, just click on "crigby" in the handle section.
Peace,
Clarke
