Lesco belts

I have acquired an older Lesco that was left in the barn of a farm I purchased and have been tinkering with it to see if it is salvageable. It is missing a few parts including the belts. I am having difficulty determining what the belt size and lengths go to this machine, Any help would be appreciated.
It is a zero turn rider model number 707201 with a Kawasaki FH601V DS08 motor.

Thanks for any help
