I have a 46 in Troy built horse XP that we have been having issues with for about the past year. The transmission belt falls off quite frequently. Initially i believed it was due to when we put the machine in reverse, but my brother thinks it happens when we fully engage the brakes. We had the pulley and belts all replaced within the past year, and thought it was fixed until today when the problem happened again. We have had it both at mechanic shops and worked on it ourselves, but the problem keeps happening. I'm not sure what we should look at next to fix the issues so wondering if anyone has any ideas for us. Thank you!
