Anyone know the proper belt sizes? This thing was seldom used and the deck belt broke after I got it going and mowed maybe twice (the one between the crankshaft and deck). I tried sizing it at Tractor Supply bought a 60 inch and it was so tight it was basically crankshaft to deck, couldn't get it around the pulleys to turn the blades on and off. Their sizing machine obviously didn't do the trick

In the process of investigating this I looked at the transmission drive belt and it doesn't look too hot either. Coupled with the odd twist it makes I'd just as soon replace this as the same time I'm doing the deck belt.

Anyone know the proper belt sizes for this machine? Any markings on the existing belts are long since gone.
