To get you the right belt spec's I'll need your Model and serial numbers. Once I get those I might be able to get you the spec's. I will strongly suggest you find a dealer online that will ups you the stock belt. Aftermarket items are good in some areas, belts is not one of them. If you go to the hustler website "hustlerturf.com" there is a link at the bottom of the page that will lead you to manuals for your machine.
