Hello everyone!

I am in need of sage advice and guidance on my Cub Cadet 108 and 44 inch belly mowing deck. I keep going through PTO belts! The last one (new) only lasted a few mowings of a 1/4 acre flat lot!

I don't know what I'm doing wrong with these things! The three spindles turn freely, and turn in unison with each other (when testing the mower deck while it's unattached to the mule drive).

I have attempted to adjust the belt as the diagram on the front of the mule drive indicates, but I experience the belt jumping off fairly frequently, and ultimately the belt breaking, which seems to me to clearly prove I have it installed incorrectly.

I have been using a 3/8' by 78" v belt. It this correct, or should it be longer/shorter?

Any ideas would be great; I'm really getting frustrated!

Thanks in advance!!
