Customer Question

I have a LA 145 this year I've gone through 4 deck belts the last time it broke the belt wrapped around the drive pulley.
I took the deck off and cut the belt out but when I started the mower with out the deck the whole mower viberated and shook and made a bad noise like something bent.
Do you think the drive pulley shaft is warped ?

The belt was caught in the drive pulley
Expert:  Bradley Martin replied 1 year ago.

Number 14 is the drive pulley I would check and make sure it is not bent like you saying the only thing that can cause the vibration with out the deck is the drive pulley might still have some belt pieces stuck in it
