I have an 18 horse Murray mower that I need my diagram every time I change the mower deck belt. It has a hard to remember wrap around the pullys for 3 blades. Go to a Murray dealer if you have to and they can look it up for you to copy down. Don't forget to bring the model number of your mower so they can look it up. Also......bring a pencil and piece of paper for your notes.
Good luck...!
