I accidentally cut the throttle down from high to low while the PTO was still engaged for mowing and the belt blew off the idler wheel and got jammed up. I think this spring is supposed to be tight, did it stretch it? or is this how it's supposed to look? Also, good thing it did happen, 2 of the 4 bolts holding the mower gear box on were missing and the other two were loose. So check your bolts !!! I found the two missing bolts on the deck. Pictures attached.
