Hustler Raptor SD 60" Belt Size?

[Hustlahh]

Any one know the belt size? I cant find it listed anyhwere online and didnt think to measure it before I left for work.
The part number is 604711. I was looking to find a replacement at Tractor Supply. The Hustler belt goes for $60!
Mower has 20hrs on it and the belt broke. :-(
