Can we have a bit more information please? Is this a new problem on a previously good working deck? Had the belt been tightened prior to the problem occurring? Had the deck or mule drive been removed or the belt replaced recently? Are the idler pulleys on the mule drive turning freely?

Mower is new to me had this problem pretty much front the start. I tried two new belts same thing. Idler pulleys turn free and I have not had the mule drive off. I did take the deck off and grease the spendels.

do you have any pictures of this problem ?  both the pto and drive belts are the mainstay of these tractors, they are basic and simple in there application and installation, there must be something ,that would be obvious to this site ,that will help you, if we can see it . any possible detail will help us help you, Pete

Take a look at pages 2 and 3 of this manual and confirm that your mower is properly mounted including the "fork" in figure 5. Don't know if this is your mower model, probably not, but the mounting procedure is the important part.

I think I figured it out. I did not have the belt tight enough I tensioned the mule drive before I started. I will find out for sure next time I mow.

Do you have the cover / guard on the Mule ?

 

This also keeps the belt on as it sits quite close to the pulleys.

I have a question. I have a 308-8. My belt dosnt come off but it wobbles pretty good when engaged. Making the belt tighter or looser dosnt seem to help. Belt is brand new. Is that normal ?

Is the center pulley on your deck straight and wobble free ?

 

I have lots of used pulleys here that are not straight.
