I need to find the dimensions for the belt on a 1999 yardman tractor the oem part number is 742-0485 according to the parts manual. The tractor is second hand and I believe the belt on it is incorrect and it keeps throwing the belt and cutting it .Thanks

Do a search for yardman tractors, you will see several. Now do your search for yardman tractor parts and place your part number and there you go. Order it.
