Welcome to the forum. Have you replaced the belt with the correct one? Have you checked all the pulleys to make sure there isn't a sloppy bearing? Does this have the spring loaded idler for the tension? Does it move free?

Also, inspect the belt closely.  If it has a busted cord, then it'll come off every time.  If there's a spot in the belt that just doesn't act/look like the rest of the belt, (twisted/curved) then it has busted cords & is a goner.

Where does it throw the belt?  At the engine or at the deck pulleys?

Sounds like a frozen or stiff Idler pulley.

the belt is coming off pto clutch. I had it where the pto switch was turned on the belt would stay on untillthe blades started cutting the grass. There is a box with a pulley on each side and a tension adjustor knob. The belt has some wear. i bought a new belt but it was the wrong one. Another trip to town.

That box with the pulley on each side is the mule drive.  Those pulleys can go bad too.  with the mower deck drive belt off of it, spin each by hand, listen to how much noise they make.  If one of them is squalling some yu might replace it too.  Go online or go by your local JD dealer.

Had some busted cords as I figured.  Been there myself.  Thanks for updating!
