Finally got a response from Troy Bilt customer service and it seems that I will be going around in circles with them. Here is the reply I got from them: As a manufacturer, we provide a limited warranty with each of our products. The written warranty can be found in the owner’s manual. We ask that customers utilize a local Troy-Bilt Factory Authorized Service Center for determination of the cause of the failure of the product. The service center would be able to gather the necessary information and provide it to our Customer Service Department to determine the best course of action. For further assistance with this issue, please contact one of our authorized service centers in your area. Title: Where can I get Troy-Bilt service? URL: http://troybilt.custhelp.com/cgi-bi.../std_adp.php?p_faqid=262&p_created=1035203510 We certainly expect our equipment to operate for a number of years before requiring unusual or expensive maintenance. Our policies are established to be fair to all owners and we apologize for any inconvenience that has been experienced in this matter. I was hoping for a happy quick fix from them but now I guess I have to take it to my local service center to have them assess my problem and see if Troy Bilt will take care of me. I will be going there tomorrow and I will post what the service center has to say.
