There is a diagram for the deck and belts in your owner's manual. You can view the manual online at Manage My Home.
On the home page, hold your mouse over the square labeled "HOME" in the upper left of the page and choose the option "Products and manuals" from the drop-down menu that appears. (If you already logged in, go to the red tabs on the upper right of the page and click the Magnifying Glass icon instead.)
In this case, enter the following information in the search options:
CATEGORY â??Gardeningâ?? BRAND â??Craftsmanâ?? MODEL # â??917276010â??
Choose â??FIND MANUALSâ?? and then scroll down to the search results at the bottom of the page and use the blue â??Ownerâ??s manualsâ?? link to open the manual. Diagrams and information on removing and installing the deck belt start on page 21.
You can save the manual to your Manage My Home profile or, on most computer systems, save a copy to your computer or print pages while viewing the manual online.
There should also be belt diagrams on the lower left hand side of the tractor itself near the footrest and just above the mower deck. If the decals are missing you can order new ones through your Sears Store or Sears.com using the part numbers 71.917.146047 and 71.917.175291.
