Belt replacement Z231KW-42

[Armadilo]

Is there a table of the belt sizes, Z231KW-42, the 42" deck uses a 5/8" not sure about the length.
Any advice input appreciated.

Isn't there a number in the old belt?

Or take the old belt to auto parts store (Napa etc.) where they can measure it for you.

Brand new model. Is this a warranty failure?
