There is what they call the spindle assembly. Some times if the bearing is not lubed enough or just plain old it will sieze up . When this happens the pulley shears off of the rod it spins on. The deck must be removed and you can buy a new spindle assembly. In most cases you need your old pully however or you will need a new one of those as well. The other possible solution could be the bolt came loos and it simply fell off . In that case you need a new pulley , bolt to hold it on , and a washer in the middle. Good Luck I just had this same problem on a mower I purchased to fix up. It cuts great now.

Your mower uses the #144200 belt by A.Y.P. This belt is 1/2" by 88.3" You must use a wrapped belt for this application. The #144200 is available through www.searspartsdirect.com and will also be readily available at your local repair shop.

Place the deck in the lowest position using the hydraulic piston (if applicable) or the manual cutting-height adjuster.
Remove the deck-to-PTO belt from the PTO by releasing tension on the idler-arm pulley. This is a spring-loaded handle that turns in only one direction by hand and relieves the tension on the belt. Slip the deck-to-PTO belt off the PTO pulley after the tension is relieved.
Remove the deck from underneath the mower or tractor.
Locate any belt stops and loosen them with the ratchet wrench and proper socket. Belt stops are located on the deck and are the small metal brackets that guide and secure the belt to the pulleys so it will not jump off when under heavy use, or stretch from normal wear.
Remove any pulley covers by removing the retaining screws using the ratchet wrench and a socket.
Loosen the idler-pulley retaining bolt (located on the underside of the mower deck) to replace the deck-to-PTO belt. Removing the bolt is not necessary. Loosen the pulley enough to wiggle the belt free from the pulley and remove and replace the belt.
Remove any arbor covers (if applicable) that conceal the arbor pulleys by removing the retaining screws with the ratchet wrench and a socket to replace the mower arbor belt.
Locate the tensioner pulley on the mower arbor belt to replace it. Loosen the tensioner pulley bolt enough to slide it and release tension from the belt. Remove the belt from the arbor pulleys and replace it.
Slide the tensioner pulley back leaving about 1/2-inch of play in the belt and tighten the bolt. Reverse the procedure to put the rest of the mower deck back together and reinstall on the mower or tractor.
