Hi Jeff, If you look at the deck, one or more of those pulleys is a tensioner, It pushes against the belt to tighten it, The rest of the pulleys can be identified by the fact that they only have a bolt through the middle, whereas the tensioner is mounted on an adjustable arm with a slot to allow adjustment. It should also be the only one that the belt doesn't go around the pully it just pushes on one side.If the tensioner arm is all the way to the end of the slot, the belt is streched and will need replaced but sounds like it may have come loose. Some of these decks also have a spring on the tensioner arm and those come off from a stick or other debris. Check it out and if you have a problem let me know and I will try to come up with a diagram. If your mower is that new there should be a belt diagram on the deck. i will need a model number of the deck or mower for that. Good luck!

First off, confirm that the tractor is in Neutral and the deck is not engaged. You also need to be on the seat, and in some cases your foot must be on the brake. Then try it.
If by "jump" you mean essentially connect one end of a jumper cable to the battery power coming to the solenoid, and the other end of the SAME jumper cable to the 6 gauge (+/-) wire on the other side of the solenoid that goes to the starter, and it cranks, this means one of two things.
More than likely it is the solenoid that is bad, but the only way to confirm this is to make certain that when you turn the key, it sends power to the small (18 gauge) wire on the solenoid. This is easy to check with a test light.
If power is goes to the solenoid when the key is turned, but the engine fails to crank then the solenoid is bad.
If no power is there, then the problem has something to do with either the ignition switch or ignition wiring, or more likely it is a failure of one of the safety switches, under the seat, transmission in gear, sometimes if the deck is engaged, or other.
One way to confirm that the problem is with a safety switch or ignition switch and rule out the solenoid would be to jump a wire directly from the positive terminal to the small wire on the solenoid that comes from the ignition. If this causes the engine to crank, then the solenoid is OK.
