A pull start mechanism is used for many Troy-Bilt tools from lawn mowers to trimmers. Occasionally the cord may become worn or damaged and must be replaced. You do not need to hire a professional to have the rope replaced. With a few tools from your garage, you can replace the cord yourself and get your Troy-Bilt tool up and running again.
Disconnect the spark plugs to ensure that your Troy-Bilt tool does not accidentally start while you are working on its interior parts.
Remove the outer cover on the tool's engine compartment. You will need a screwdriver to remove any screws.
Locate the pull string and make a note of the direction in which it is placed. The new rope will need to face the same direction for the engine to start properly. If necessary, write the information down or sketch a quick diagram with pencil and paper.
Remove the pulley and unwrap the old cord. Thread the end of the new pull cord into the hole in the center of the pulley. Tie a knot in the end to secure it.
Pull the new pull cord tight to make sure the knot is secure and will hold the new cord in place.
Wind the new cord around the pulley in the same direction in which the old cord was wound. Replace the pulley system back as you found it. Refer to your notes or diagram to ensure you are replacing it in the same direction.
Reconnect the spark plugs and replace any other cover you removed to get inside the tool. Test the pull cord by starting the tool.
