So a few days ago i was mowing and turned off craftsman mower model number 917.259550 because i noticed a lot of old grass under deck. So i got back on started mowing turned Blades on starting cutting grass then heard a pop. I have the gas tank off but it seems this craftsman don't have a blade engagement cable? I have looked under the deck and see no place to put any springs. And the blade level is very hard to push up now.
