LT125 (LT23420) Deck Belt Size

[TiIngot]

Snapper Model number is 2690875, Serial number 2014719099 42" deck. I have found reference to two belt sizes, 91.10" and 94.45". My old belt is shredded so it is no help. The different belt sizes references one for a shallow groove pully and the other for a deep groove pully. How do I tell which size belt fits my pully's other than buy both and return one?

First the seven model number is coming back as Allis-Chalmers 46" cut so using the serial number I get 2690872.

And there four different decks that it can be per the IPL. Basically you know if your has shallow or deep pulleys and choose one of the Kevlar belts.

Snapper dealer could not tell me which belt size I needed from model numbers however she sold me the 91.10” size because she said she rarely sells the other size for Snapper. It fit!!!
