if you can determine your tractor's model # from the linked list, go to sears parts webpage to see if they still list it.

Here is a link that might be useful: Sears Suburban Model # listing

tried that site. they only list the drive belt. thanks

Any luck utilizing the deck #s? We had a 69- and I seem to remember 137 or 139" written on the shield... Gulp. I gleaned this site from someone here. Maybe it will help.

There is a manuals section- in which the part #6517h came up for a 48" deck primary- which coverted on the belt guide as a 5/8 by 100" . There may be others.

thanks, i did a rough measure using a way longer belt from a cub cadet 169 tiller drive belt and came up with about 96" so i t could be 100" thanks for your help.
