The 48" deck takes a "B" section belt, 91.68" long. You can try a B88 or a B89 Gates. One is a little short, one is a little long. O'Reilly's shows the cross of the CCC part number to a Gates 6757BR, but I'm not convinced. It shows it's a little long. I'd check it. Or...... go to CC and get the right belt, the first time no worries and it will last a very long time.
