I need to find the manual for this mower or instructions with pictures to replace the belts. It is model 917-272233.

lramsey512,
Go to this website and you will be able to get the parts lists, and see the diagrams, and print them off for easier use.

Goto:
Dixiesales.com

Click on : parts list (on left side of screen)

Click on: to see more Sears parts click here

Then enter your model #, and you can view the different areas of the tractor, and then view the parts lists.
Good luck.
