Goodday to all. New to the site so I hope someone can give some help. I have a Craftsman 944.601171 17.5 hp, 42 in deck. Anything I can find for the deck belt calls for belt pt# 144959 which is 95.5x 1/2. I have checked the routing 50 times if I did it once, this according to the diagram on the deck. VERY simple routing. There is no possible way that the belt will work as it falls off the engine pulley when it is engaged. I am hoping someone else has run across this problem and can give me some hope of ever getting the right belt. I have tried all kinds of length of belts . A 92x1/2 comes the closest. Thanks in advance.
