I am looking for the Gates belt numbers for the drive belt and deck belts. I believe the drive belt is 94 1/4. The deck belts are 88 and 79.3 inches. All are 1/2 belts.

Sears likes to keep their cards close to their chest. Part #57 in this link is what you need for about $26 but they don't tell you the size, just their part number. http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Riding-mower-tractor-Parts/Model-917251472/0247/1509200/10043839/00003?componentDescription=&brandDescription=&searchTerm=57#Partslist If you download the manula or have a hard copy it should tell you the size

There are different width belts, the belts on your mower are 1/2
Luck

Dah Huh Duh Huh Yep That's all folks

What's your deal Bill ?
You asked if all belts were 1/2 inch
And I said no.

The belts are 1/2 inch. Bad information is not all that valuable.

drive belt 123796X = GB 6895
deck belt 131290 = GB 6888
pto belt 154746 = GB N/A
