  If the wheels or tines on your Troy-Bilt Tiller aren't turning, it could be due to improper use of the controls. Review the Operation section of your manual. It may also be caused by worn, broken, or misadjusted drive belts, in which case you should replace or adjust the belts. A loose bolt in the transmission pulley can also be the culprit; try tightening the bolt. If these steps don't resolve the issue, it could be due to internal transmission wear or damage, and you should contact your local authorized dealer.
