Cub Cadet LT1045 deck belt jumps off on lowest setting

[NorthBama]

model 13AX11CH712
Deck belt jumps off on lowest setting. All the pulleys seem to be ok. I did notice the belt runs high on the tension pulley. Anyone out there in Cub land have any issues with this model.
Thanks for any help

:welcome:
At the highest & lowest position the belt is furthest out of alignment so most likely to jump off.
Not much you can do other than changing the pulley for a wider one with a thicker flange.
If you regularly mow at that height then you can pack up the fixed and sliding pulley with a few washers.
Bending them slightly outwards can also help keep them in alignment.

Thank you for your input I will try some washers under the pivot point of the tension pulley bracket. This is a bad design with no belt keepers for the pulley.
