I reviewed the belt chart info provided and it refers to a 3/8 x81 inch belt for the 42" mower. I checked TSC today and they hadn't had one, single 3/8 by anything belt. The major chain auto stores carry nothing bigger than 76-80 inch 3/8 belts. I entered the IH CC part number in many searches and it comes up 1/2 x 811/2. I have no hair to pull and the lawn is not gravity challenged any more! Can someone slam dunk me mowed?
