Lawn mower cords withstand a great deal of wear and tear. They will eventually snap, possibly right when you are ready to mow your lawn. Exposure to the sun and other elements can cause a breakdown of the cord material. This intensifies when you are pulling hard on it.
Remove the spark plug wire from the spark plug to prevent the mower from accidentally starting. Remove the screws holding the starter housing in place. Depending on your manufacturer, these may be located behind the gas tank. Check your owner's manual for the correct location of the screws. Remove the plastic casing.
Cut a section of new cord to 10 feet long. It can be trimmed for a better fit after installation. Thread the cord into the starter pulley, located inside the starter housing. Tie a knot in the end to prevent it from pulling out of the pulley. Wrap electrical tape around the end to secure the frayed ends of the rope. Wrap the cord around the pulley two times.
Thread the string through the hole on the starter housing. Replace the starter housing on top of the mower. Fasten the housing in place with the removed screws. Reattach the gas talk if removed.
Thread the starter cord through the hole on the mower handle. Pull until there is a slight tension in the cord. Attach the T-handle to the new cord at a comfortable height. Slide the cord into the T-handle and squeeze the staple on the bottom of the handle closed around the cord. Trim excess cord length.
Replace the spark plug wire.
