Are you still looking for that belt diagram..? Is this for the motor to trans (which is pretty simple) or the belt for the deck..? Couldn't find a diagram so hope my drawing comes out right.. This is for the "deck belt" routing..!!!
Back of mower is up here on the top..
Left pulley (O\ /O) Right pulley
.......Tension \ \@/ / Pulley
.............Engine \ @ / Pulley
Front of mower here, where the motor is..
Main thing is, you take the belt from BETWEEN the right & left pulleys, pull it down and around the tension pulley..
Hope this helps.. Think I have the same Sentinel..

Go to Craftsman, Order Tree or Parts Tree.com and input your model number. Choose the correct tab and go to the mower deck. It will give you a good over view of how the belt routes. Hope this helps.

Hi,

You will find the diagram on the left side of the deck as you sit on tractor by left foot. It will be located under the foot pedal that has the routing diagram specifically for your Troy-Bilt mower model. Note that owner's manuals may not have the most current schematic.

Also you can check this link to download the diagram:-

The routing is usually pictured on the belt cover such as in your picture. If you send me the model no. to the rider, I will verify proper routing.
