Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist you.
It is very likely that you have an idler pulley, that has a worn bearing, that is seizing.
It will be either one, or both. The best way to determine which is actually at fault, is by removing your belt from each of your idler pulleys, then spin each pulley by hand.
The faulty pulley will spin with lots of resistance, or make a rumbling noise ...
The smell of belt, is a true indication of a bad idler pulley.
You can also lock your parking brake, to loosen your belt enough to spin your idler pulleys by hand.
Thanks for checking. This confirms that your front pulley will need to be replaced.
It is very doubtful that your transmission is our problem. The frozen idler is at fault.
You are very welcome! I truly hope all goes well for you.
Thanks for double checking. The rear pulley will need to be replaced instead ...
Your transmission pulley, and the pulley under your engine is definitely not our problem.
The pulley that has a fan attached, is your transmission pulley. How many idler pulleys do you see?

you are not driving me crazy. This is why I am here. Take your time. You are correct. Your belt goes from your transmission pulley, to the double pulley underneath your engine. In the middle is two idler pulleys that are there to keep your belt tight.
I do believe that one of the pulleys in the middle is causing our problem ...
Your mower deck belt will not affect the spinning of your idler pulleys. If you remove your mower deck, you can get a better view of your pulleys.
