Troubleshooting: MTD Yardman 46" PTO Belt damage

Old belt was worn bad, replaced it today. The new belt lasted about 5 minutes, heavy smoking and next thing I know the deck isn't cutting.

Belt failed! never saw anything like it.

What the heck could cause something like this to happen?

Something was installed incorrectly (belt rubbing on metal) or a pulley is frozen. The smoking tells the story.

smoking came from the engine pulley area.

took the deck off, raised the tractor, got underneath, noticed the tensioner assembly in the middle - comprised of 2 idler pulleys mounted to a bracket that is spring loaded. the spring is fixed on the idler assembly piece, but was hanging loose on the other side, appears it should be hooked to something solid. perhaps improper tension caused the failure, but still, for the belt to fail that quickly?

unless there is a misalignment somewhere...........

If it was smoking, 5 minutes was probably generous of the belt. It's rubber and string.
