How do you replace a John Deere LT133 transmission belt?

Answer 1

I would think you arereferring to the drive belt. First thing to do is remove the mowing deck. From there you will find a spring lever that holds the belt tight. You will need to take a bar or wrench and release the tension on the belt and take the belt off of that pulley. Then from there it is a matter of loosening the pulley next to the frame and snaking the belt from around all the other pulleys in order to get it off. To install just do everything in reverse. In order to gain access to every thing it is best to stand the mower up on the rear wheels, you will need someone to hold the tractor in this position while you remove and install the drive belt. Just recently done this and the job is not really to hard. Just take your time as to not remove unnecessary components. You will have to loosen some of the pulleys but none have to be removed as I remember.
