Check to be sure the belt is the correct length and check the belt guides to be sure they are close to the pulleys.

Anytime I ever had this issue if I tightened the nuts on the tension spring to the brake/clutch the problem would go away.
I also noticed at times when I would push the clutch/brake peddle down hard and fast it would cause the belt to pop off especially after the tractor warmed up.
