I have a older grey craftsman 42" ride on lawn mower with 15.5hp and the lower belt was loose and not cutting the grass properly. Upon furhter inspection, I realized the belt was off one of the side pullies and upon trying to repair it, we were able to put it on the side pullie but unable to put it back on the front main pullie. Is there something we should be have to loosen or a spring that needs to be pulled to make the belt fit?
