Small Engines (Lawn Mowers, etc.): Deck belts, scotts lawn tractor, measure thanks

Question
Hi, I have a second hand Scotts lawn tractor, made by Murray, that needs both the primary and the secondary deck belts. I do not have a manual. The model number is 46572x8.
You are my last hope before I try using a tape measure. Thanks,  John
