Ok... so, couple things.
If you have a frozen pulley, you wouldn't have mown for an hour before you burned the belt off of it. It might have lasted oh..... 45 seconds at WOT before it would have started squealing and screeching and smoking then possibly even getting close to fire before it broke.
Second, the belt was hot. Well bud, that's normal for a belt that makes a couple bends and is driving a deck. They do get hot. That's how friction works.
Third... if you do have a locked up pulley, or one that is going out, it probably just failed. Once the bearing starts to go it won't last long at WOT. Should be a pretty simple thing to diagnose. I'd be checking the spindles too. Does it have greasable spindle bearings? Do you ever grease them?
