917.270514 14.5HP 42" Deck Craftsman Riding mower Squeaking

my 917.270514 14.5HP 42" Deck Craftsman Riding mower started squeaking today. So i turned off the blades and it continued to squeak. Sitting still running it doesnt seem to squeak. Is there some place I have to lube? I havent found a place for me to do that.

Help.

Check all the idler pulleys from the engine to the tranny. They are not able to be lubricated easily, but the bearing might be going out in one of them.
