I hope this does not sound terse, but you are going to have to provide more specific data than "an older mower". Brand of machine, model number of machine, and the deck cutting width are all variables that can have different belt routing and pulley arrangements if even one of the variables is changed. Without specific data to possibly allow someone to view an online owner's manual or service manual I can only offer the following advice: Deck belts are typically configured as "Vee belts". They have a Vee side and a flat side and in use, both sides of the belt make contact with a pulley at some point in the belt path. BUT.......THE FLAT SIDE OF THE BELT MUST ONLY RUN ON A FLAT PULLEY AND THE VEE SIDE MUST ONLY RUN ON A VEE GROOVED PULLEY. IF YOU SEE ANYWHERE THAT A FLAT SIDE IS RIDING ON A VEE GROOVE PULLEY, OR VICE-VERSA, YOU HAVE THE BELT ROUTED INCORRECTLY.

Thank you very much millworkman. I am going to query the contractor to find out what they will use for the deck framing as that was not listed in the estimate. I don't know if he plans on using the current framing or not, but will find out. Ntruro, I don't mind the grey at all, but thanks for the insite.
