There are three 1/4" holes around the perimeter of the pto pulley. There are coresponding slots in the basket pulley to access the set screws. You have to put pressure on the thrust button to release the pto pulley and turn it until the slots line up with the holes. I use the pto lever on the tractor which can be difficult but works for me. I push and turn at the same time. It usually doesn't take much. A gear puller will work too. Once you get the holes lined up you should find two set screws per hole. Now's a good time for a little PB Blaster or the equivilant. First out will be a very short set screw then a longer one which should have a pointed end. Once all six are out the fun begins. I use a long, blunt punch to tap the pto pully NOT the basket pulley. I run the punch in down by the points cover at as much angle as I can get. Tap then turn and repeat this until you notice it becoming loose from the bearing. Don't hit the punch hard, just tap and turn. I have gotten very stuborn ptos off using this method. Use a little patience as well.
If you're lucky you'll find two jam nuts behind the pto that held that loose bolt. I did once myself.
Good luck!
