You can download the User Manual here from ManageMyHome,

(Just copy, and paste the above into your address bar, then press the Enter key)
On this page where it has Go in the blue square, go below that, and click on -> View Manual.
This is a PDF file download. Took me about 12 seconds to see the first page, (I have Medium speed DSL )

Page 22, (Service and Adjustments), starts showing the routing of the belts.
The deck belt makes a T shape. It goes around the two mower blade pulleys, (Mandrel Pulley), and then around the engine shaft pulley. There is a tension pulley is on the left side, it's on the outside of the belt, and pushes IN on the belt. There is a tension pulley on the right side. It's on the outside of the belt, and pushes IN. (Pushes in. Pushes towards the center of the mower)

The Motion Drive belt goes around the rear end pulley, (Transaxle Pulley),
goes up the left side of the mower, to a pulley that is mounted solid to the deck, (Stationary Pulley), comes to the inside of that pulley, then goes to the outside of the Clutching Pulley, up around the engine shaft pulley.
From there, it comes back along the right side, to all the way to the Transaxle Pulley.

Should you wish to save a copy of the above manual, it's easy. In the header bar at the top of the PDF file is a Floppy Disk icon. It's the second icon from the left. Hovering your mouse cursor on it, will briefly reveal,
"Click to save this file to your computer or another location"

You will then see a ->Save a copy:, small window come up.
At the bottom of this window is the Filename:, box.
Put your mouse cursor in the box right after the -> f, in .pdf
Left-click Twice. Make 1 space with your spacebar. Now type ->
Craftsman 42 inch Mower Manual. Then go to the bottom right of the window, and click on -> Save.

If you do not have your downloads set to download to your My Documents folder, this will go to your desktop screen. In any event, just double-click on it to open it. You can also burn a copy off to a CD.
(If you do not type Craftsman 42 inch Mower Manual, or something you will recognize later, you will be going around looking for ->L0901538.pdf)

As long as your deck mounts match up then you should be good to go. You might have to change to a different sized belt though. Other than that everything should be fine.
