Cub Cadet RZTSX54 Transmission drive belt jumping off.

[mboessen]

Hi, All:
I have a Cub Cadet RZTSX 54 steering wheel zero turn. (Greatest mower ever!) 2 years, no problems. Yesterday while I was mowing, the transmission drive belt jumped off. I got it back on there and it looked fine. I thought maybe a stick popped in there. Finished mowing and parked it to clean the clippings off the mower deck, and when I got back on it, the belt was off again. The belt guards all look fine, and the belt looks undamaged. I can't see any reason this thing is jumping off the pulleys. Anyone have any experience with this problem?
Best
Mike

Unless you have x-ray vision you can not tell if the reinforcing cords are in good condition
Having said that check that the tension arm swings freely ( when did you last lube it ?)
And check that the pulley rotates freely with no noise
