Thank you for your question.
I am sorry you are having a problem with the tractor. I will be happy to help you. Over the years, we have sold a few different models of the LT1000 and the belt routing changed slightly. I have posted an image below that has the instructions for replacing both belts. Just click on the image to enlarge it. If the instructions do not match your model, please reply below with the model number off the tractor. The model number is located under the seat and should begin with 917.
I hope this is helpful.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
