Thanks once again Bruce, for you great work helping me out here.. I didn't know that Part number (2691235-00) until today when I went back out there and triple checked all over the mower to see about any other numbers were on it.
I can't believe that Victa has One Parts Manual for the Briggs Engine & drive Belt, One Parts Manual for the mower and a third Parts Manual for the Deck.
But at a local mower shop today they couldn't find any pictures or part numbers for the Deck Belt or the Deck Belt Layout Diagram or even the pulleys on the deck. Except for the spindle pulleys.
Cheers
Steve
