I have a 13-32. It is similar in style to newer models. I think it would be pretty much the same for yours!! Mine is similar to the picture in Aussie86999 post
I have changed both belts on mine so if is similar I should be able to help.
Is it the cutter belt or the clutch belt?
Let me know and i will run you through how I did it.
If it is any help.
